I'm an engineer and this popped up in my recommendations. Don't know why I clicked but I watched the whole thing. I use solidworks this way pretty much every day, and I felt this was all perfectly explained. Wish I had a teacher like you!

Hello, I am a graduate mechanical engineer and I work with SolidWorks. At the moment I am learning finite elements and I am enthusiastic about her lessons. You are the best teacher.

Note at minute 56 onwards is probably one of the most valuable synthesized and elegant pieces of information that you could ever see in your career as an engineer. If he added some of st venant's principle it would have been absolutely perfect. Very useful video.

@ManuelRamsaier 2 года назад

Thats a great lecture :) I like the concept of basically asking your students to apply their best knowledge first, then show something which they would not have expected (so you have their full attention) and then showing them why is that and how it can be considered. Good job and thanks for sharing!

@lukehunter2362 2 года назад

I wish I knew about this before my FEA class… This is very helpful thank you. I wanted to note, at 29:00 when discussing curved surfaces causing element distortion with Solidworks you can apply mesh control locally to that surface instead of refining the mesh for the entire model(generally half the element size of the global mesh is standard). This will save you time and computer memory when running the mesh.

@aries6776 2 года назад

Good tip. I do the same. The way I choose on which bits to locally reduce the mesh size is to first run a coarse gobal mesh and then when I get the areas of stress I increase the resolution in those regions i.e. holes and other interfaces.

@MehmetSUN 9 месяцев назад

Hello. I downloaded almost all your videos and learned a lot of information thanks to you. In the analysis you made with the Solidworks program in this video, at minute 47:30, the r/D ratio should have been taken as 0.1/3 instead of 0.1/2 in the notch graph. A lower value emerged than the program's conclusion. With 0.1/3, the K value seems to be approximately 3.12, which gives a value of 15600 psi, which is quite close.

@TheBomPE 9 месяцев назад

Thanks for the words of encouragement. The charts I'm using don't require the r/D ratio, only D/d and r/d. D is the larger width and d is the smaller width, based on the figure included on the chart. I believe the correct point was found on the correct curve in the video. Thanks for watching!

When I speak of "reference material" in this video, I'm referring to a document we have compiled that contains all of the required reference information used in this course. Mostly this document contains material found in our textbook for that course (Statics and Mechanics of Materials, 2nd ed. by Riley Sturges and Morris). Outside of this specific course, I would encourage engineers to search for the most relevant and up-to-date reference sources for their specific needs. Peterson is a good source for stress concentration factor charts. Thanks for watching!

@SeracS354 4 года назад

Hi - thank you for making this lecture available. Should stress concentration factors be used for ductile materials?

@TheBomPE 4 года назад

There is a stress concentration whether or not the material is ductile, but as I discuss at around 56:40 and following, stress concentrations can often be safely neglected for ductile materials. Whether or not you should neglect them is controlled by whether you can tolerate tiny amounts of permanent deformation at the concentrated locations. Thanks for watching!

@SeracS354 4 года назад

TheBom_PE hey that clears it up, thanks. One last thing that has been confusing me - There was a question in Shigley textbook of the sheer stress in a double shearing pin. The solution didn’t use ‘sheer stress = V / A’ as I would expect but ‘sheer stress = 4V / 3A’ which is the formula for translational sheer stress in a round beam. I thought you would look for the sheer across the pin, not along the pin?

@jerryasemota8286 2 года назад

Great lecture and wonderful lecturer. I can understand why you are using psi( American units) instead of S I (International) units N/mm2. Now, it is clear from the results obtained from the analyses that the stress concentration is in the neighbourhood of the hole. Now, if the plate(say Steel) is used in building the deck of a ship and opening is provided for access, how can Solid work take care of reinforcing rings around the hole using triangular or other elements? Finally, are these lectures available as hard copy?

@TheBomPE 2 года назад

Thanks for the encouragement! In solid works you can model more complicated geometry and loading scenarios than what I did here. So if you want to investigate a reinforced hole in a ship deck, I would expect you could come up with some reasonable way to limit the bounds of your study to do that. I'm sorry, right now I don't have hard copies available for my lectures. Thanks for watching!

@shamusmon 3 года назад

Great lecture! I have a question though. What if the problem is outside the bounds of the stress concentration factor graph? e.g. if the r/d value is greater than the range on the x axis of the graph. What are the implications of this and what should you do instead? Thanks!

@TheBomPE 3 года назад

If r/d is greater than the horizontal range of the chart, you have a few choices. (1) Look for a similar chart that has more range. (2) A conservative thing to do is use the K value at the rightmost point on the chart you have. (3) A non-conservative method is to roughly project the slope of the right end of the curve further right. (4) An even less conservative thing to do is ignore the stress concentration effect entirely since r is "large." (5) Occasionally you might be able to find or create an equation for the curve you are using which will enable you to more accurately project outside the curve's range. If you go to the left of the curve's range, K is obviously increasing rapidly because the discontinuity is becoming sharp. At some point a plain stress concentration factor technique is insufficient, and a fuller, fracture-mechanics-based analysis is called for. If you are interested in a brief intro to fracture mechanics, check out these videos: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SD6qITe3-Xo.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E5tgDVN1zy4.html

Hi. Thanks for sharing this. Aroud 47:30 you found slight differance between the FEA result and result you got from formula. The reason of that differance is that you used r=0.5 in in formula but 0.1 in in Solidwork. And ım suprised nobody in class told this to you :)

@mattlegere376 3 года назад

No. He did it correctly. The reason the stress values are so different is the effect of the hole in front of the reduction in part thickness.

@FrenchieYang12 2 года назад

In regards to this, I was also wondering why he used 0.5 rather 0.1 in the main formula when he changed it to 0.1 in solidworks specifically for the fillet. I understand 0.5 didn’t give any stress at the fillet location, which explains that 0.5 was a good choice to reduce stress. Did he purposely changing it to make it sharper to show stress, so the situation can be solved? The overall answer would be, don’t use anything less than 0.5.

Very informative video, Can I get the reference file somehow and a small question, Why can't we see the max principle stress in fem to compare with the analytical solution. Because the max principle stress will show Higher value. Basically I'm confused with whether should we use von misses or max principle stress to compare

2 года назад

Have a look on Mohr's theory and von misses theory, basically von misses includes the tensile/compressive stresses and transversal stresses (shear) and it's mostly used for failure cirteria for static ductile materials (if your allowed stress is lower than the highest value of von missed your component would start to yield. The principal stresses shows you the pure tensile or compressive stresses in your part. As I mentioned above please refer to Mohr's circle and the description of the distortion energy by von misses to better understanding and application. Also have a look on failure criterias

@HopeScreen 8 месяцев назад

i had a simple question. there are charts and correlation for the plate when the whole is not there and charts and correlations when the fillets are not there .which to use?

@techhunt4922 Год назад

ok. so if i want to calculate stress concentration factor from the simulation, i have to divide the max stress from the color chart with the stress that is away from the hole and dont have the effect of the hole. and then compare what i got as a factor to the one from the charts for D/d ratios?

@araglar 2 года назад

I keep noticing very high concentrations in very small areas in the FEAs of various types of industrial threads. These stresses are in the thread root and contact areas. Typically it’s in the first three threads that the strain is highest. Do you have any advice on how one could mitigate or defend the results of an FEA with that type of result?

@aries6776 2 года назад

That's sounds pretty accurate tbf. Most of the stress will be on the first thread, then a bit on the next and a bit less on the next (something like 34%, 23%, 16%,11%,9%, 7% on each consecutive thread). If the bolt is softer it will spread more to further threads but yeah normally 3 threads are doing most of the work. For example in carbon steel you only need 1x the diameter in length of thread engagement to maximise sheer strength, so you aim for 1.5 to make sure you get at least a 1 times. And yes stress is highest at the contact points of a thread, which you see when a thread strips. It makes sense when you think about it. The edges get rounded over. As for how I'd defend the results, well look at some pictures on the internet of stripped threads. That's how I check all my sanity check all FEA results. Do they match up with real world examples.

@thebuckstops7272 3 года назад

Hello. I'm a novice SW/FEA user who's beginning to work more and more with FEA for school. How do Solidworks' FEA simulations match up with other FEA software such as FEMAP or Nastran? When does SW not do an efficient job with finite element modeling?

Solid works in general is not that much used in FEA. ANSYS is a free software. The meshing quality is much higher with FEA dedicated softwares and will give you better results.

@E-Learning1992 3 года назад

can you please tell me difference in contact set and component contact in simulation.

@jcventura8532 3 года назад

Contact refers to how the components interact with each other (bonded, not bonded). The hierarchy in SW simulation goes as follows: Global contacts>Component contacts>contact set (local contact). Contact sets are defined between two faces/edges that can even be within the same component, these are commonly used in cases where you want to simulate interactions between faces that are free to come in contact but are also free to separate (no penetration contacts). When you choose component contacts SW requires a list of 2 or more components and it will impose the specified conditions on all faces it finds in common between those components. Because of their hierarchy, local contacts will overwrite component contacts and component contacts will overwrite global contact conditions.

Great lecture but as a European, it is really strange to have a lecture with Imperial system...

@TheBomPE 4 года назад

I do about a half and half mix of SI and US units on my channel. Currently US viewers account for triple the watch time of the next highest country (India). In the US, "Imperial" units are the ones we "feel" most natively. Here, they are also probably the most widely used units for things like raw materials, fasteners, etc. Anyway, they are still very important, particularly to US watchers, so I do both.
