Good job! In my opinion, a possible failure could be due to the fact that titanium and carbon epoxy matrix have very different elastic moduli. So, under the same load (pressure), assuming the thicknesses are similar, each material will experience a different deformation. As a result, the union of both pieces will be subjected to very high stresses. So, I see the last alternative you mentioned as the most probable one.
Hi. Im khalil. I would like to ask u if im going to test a glass, is it possible? Since it is brittle, there is only ultimate tensile strength. Pls advice.
Hi Khalil, yes this would be possible to do. Since it is brittle, the specimen will simply fracture once the elements surpass the ultimate tensile strength. You still need to apply the young's modulus so that the program can calculate how the elements are going to elongate when the stress is below the ultimate tensile strength, before it fractures. Hope this helps!
@@theengineeringguide8332 I tried to do it but don't know how to insert the uts value in the material data (engineering data). If it doesn't matter, may i contact u personally?
Thank you for the extremely helpful video. Would you please let me know if you have to add any Failure Model/Criterion in the Explicit Dynamics Material Model to get a reliable result. Thanks.
Excellent Video .But I am facing an error while doing the analysis which states "Solver energy too large" ,Can you please suggest me an approach to achieve the results. Does the configuration of laptop affect the solver ?, my laptop has 16gb ram but still I am not able to get the results. Please let me know what has to be done.
Hi, what if I want to use a general material (S275-structural steel)? Would ANSYS find a solution? What should I do to simulate the behaviour of this material in Explicit analysis?
Hello, sorry for the late reply. I hope you were able to solve the problem! You are most likely getting this error because you are editing on of the pre-existing material in ANSYS. In order to edit a preexisting material or library in ANSYS you must click the check box located in column B in Engineering Data Source. However before you add the material to the project, you want to make you to unclick the checkbox so that the edits you made can be saved. Once this is done you will no longer be in edit mode and you can add the material to your project by clicking the plus sign beside the material. Hope this helped!
I appreciate the step-by-step, detailed presentation on the use of ANSYS. But I don't understand the point of choosing "Explicit Dynamics" solver for this problem. This is not a dynamics problem at all. Tensile load is applied very slowly and inertial effects are negligible. This is a NONLINEAR STATICS problem. If you want to see failure of the specimen, you can turn ON the nonlinear effects (geometric nonlinearity and material nonlinearity) in the Static Structural solver (not in the Explicit Dynamics). Explicit dynamics solver is supposed to be used for dynamical problems taking place in very short time period (in milliseconds or so), for example, car crash problems. Using explicit dynamics to simulate a tensile test is an overkill and misleading. For those who want to learn linear vs. nonlinear analyses and implicit vs. explicit time integrations, I recommend: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZljfZ70toyY.html, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kudC1z2Rb0A.html
