bhaiya i have to do an ug project in abaqus where proff asked me to model a train track and apply cyclic load and see the result can you help me step by step as i dont know anything in abaqus.. please bhaiya help kar do.
Hello I want to model a themo-hydro-mechanical analysis. As you know, Abaqus in the SOIL option just considers a fluid. But I want to calculate the pore pressure more detaild. How do you think I can add a more accurate analysis of the temperature-dependent pore pressure to the thermal-mechanical analysis? Is it necessary to write the entire process of hydro-thermal-mechanical analysis with UEL subroutine or can only pore pressure be added in each increment to thermal-mechanical analysis, i.e. use the sequentially coupled method via inpute file or UEL sobroutine? Best regards,
Hi, If you mean to define a parameter for that in the settings, there isn't such thing; the shear failure will be calculated by the Abaqus based on the compressive and tensile material properties you have provided.
The English should be improved overall. An example: at 7:34 "The strain is abstained....the curvature is abstained..." should be "The strain is obtained" because "to abstain" means means "to not to do something", "to refrain" etc
Hello, the reason you get 0 results in stress or displacment because you didn't define boundary condition properly. and if you need a specific answer you must explain more. you contact us via our WhatsApp: +1 (740) 966-1814
Hi, thanks for your comment. I don't understand your question completely. can you be more specific? All I can say now to import a model in Abaqus, you have to use the "Import" option from the "File" menu.
At 16:00, it is stated that NTENS=12, but I couldn't understand it. Isn't the NTENS=6, and the total number of variables for strain is 12 which also makes dependent variables 12.
Hi, that depends on your relations and formulas for the FGM material. Besides, converting the USDFLD to VUSDFLD is not easy because in each one the definition of the variables could be different. If you are interested, you can get the full tutorial, which its link in the description.
Hi, to see the details of the python script and learn how to work with, you can buy the full tutorial of the package, which you can get access to it with the link in the description.
Hello, First you need to obtain the residual stress of your model. One way to model residual stress is to use "Predefined Field" tool in Abaqus. next, it's better to create a path of nodes or edges of the region of your model where you need to analyze the residual stress. after that use the "Create XY Data" tool to plot.
Hi, thanks for your comment. You see only these two options (Thermo-mechanical and eigenstrain) because that is the newer version of the AM Modeler. In this part of video, it is showing the older version, which have three options.
Hi, thanks for your comment. To answer your question, I need more detail. I mean what is your model? or which part of your model you need to plot a graph?
I have problem, I am modelling a 3 point bending system. I need to applu a boundary condition of 200 mm on the centre. The displacement is at 5 mm/min. Now I am not getting what values do i need to put in Time period, Initial, Minimum and maximum increments. Can you please explain me that?
Hello friend, thanks for your comment. The reason for the errors might be because of the writing subroutine principles, which sometimes get tricky, and in the video, you shared its link, he may did not explain everything or make some simple mistakes, or you did. The writing subroutine and coding techniques must be learned. You can watch this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NI2WQZB8730.html or you can see the full package that its link is shared in the description below.
You can define as many steps as you need for your simulation if it is logical in the simulation; you can do this using a python script which as so happens you can find an example of it in the videos of this package: caeassistant.com/product/python-scripting-in-abaqus-part1/ caeassistant.com/product/python-scripting-in-abaqus-part-2/
Hello, thank you for your compliment. The time period in Abaqus explicit means the physical time of your analysis. It determines how long your analysis want to simulate. For example impact simulation with step time equal 3 means that 3 seconds of the process will be simulated.
Thank you for the video, but when I am using the truss elements i.e T3D2, I am getting the Warning "Solver problem. Numerical singularity when processing node TRUSS-1.8 D.O.F. 3 ratio = 4.21658E+15." How to avoid such a problem.. Can u suggest me... Thank You....
Hello, thanks for your comment. check these three things in your model: 1. Check your material properties. 2. Check the Displacement you applied in your model; it might be too high for your model. 3. Check the number of elements. In a truss, each member of it must be assigned to only one element. After you checked the items above, if the problem still exists, your model must be checked completely.
Hi, thanks for your comment. There is no conflict between them. First, the velocity is applied in the initial step and then the pressure in step-1. If you mean something else or have any other questions, please explain more.
@@caeassistant7734 I am modelling a composite laminate of 8 layers along with the frame on top and bottom. I am using VUMAt code and i am applying a predefined velocity in intial on the ball and applying pressure on top frame in step one. I need all my boundary conditions and pressure on the frame has to be applied before the ball hits plate. so how can i do it
Hi there, Your response is the same that I told you before. If you need more help, just visit the consultancy section on our website: caeassistant.com/consulting-mechanical-engineer/ Or email to this address: Support@caeassistant.com Best luck.
Hi. We are uploading the "module by module" videos every week. As for the files, you can find more tutorial videos and examples with their files in the links in the description. However, we recommend you check the Abaqus for beginners playlist first then get more examples in the links below: caeassistant.com/product/abaqus-for-beginners-mechanical-engineering-copy/ caeassistant.com/product/abaqus-for-beginners-structural-engineers-in-the-field-of-civil-engineering/
Hey there! thanks for your comment. Your comments could help us grow. I have a question though, have you seen the video completely? This video is a complete tutorial of an example using the UMAT subroutine and it's not a promos video. please, watch the full video if you are interested. If you liked the video, let us know your thoughts so we can make more. Thanks anyway.
@@ahmadturani8203 as far as i understand, it is a commercial for the tutorials. The vumat implementation takes time and effort which should be compensated somehow. One cannot expect people to work for free
Since it is not a popular topic at the moment. I suggest lowering the course price or discount for the 1st time purchase. I can learn myself to implement Beso employing python to Abaqus within under a week with close to zero experience of coding (I am only familiar to use the given modules from commercial software) then you should probably consider my suggestion.
