Just a general question? If someone asks material model to use in ABAQUS, what would be a good answer? Assuming we have hyperelastic material, we have a bunch of models like mooney-rivlin or Ogden. How should we pick them and make sure we are right? I need to the procedure.

How can I check if there is a crack in any component during a snap fit assembly. Actually, there is a snap fit holding two plates. The question here is if there is a crack after assembly! How check figure this out in ABAQUS! It's a displacement control process.

I have a multilayer and already created named selections. How can I see only the named selection and other parts hidden?

Hi I'm new to ANSYS as I used to work with Abaqus. In ANSYS 2022, I don't see the extrusion tab!! Where can I find the extrusion tab? In previous versions I see it already in the tool bars. Thanks

Could anyone bring physical examples of when to use different types pf contacts like bonded, frictionless, frictional, no separation? And in bonded contact, when we talk about linear analysis, how does that exactly mean?

Hello I use shell element and I can change number of integration points along the thickness. How can we make sure we sue the optimum number of int point? Thanks

Solid elements do not support rotation at nodes. The question is that if we have bending in our problem, using solid element would Ok? Why? Thanks

Hello I created a set by nodes, but I cannot neither change it nor delete it. by right click It shows copy. Is there a way to delete it or edit it?

How does FEM find shape functions? any numerical technique? And I want to see the shape function of an element in my model, how can I see it say in Abaqus? Thanks

Is plastic strain tensor symmetric? And how may nonzero components does it have? Thanks

Does anyone know the difference in shear stress between close thin wall circular beam vs open one is?

Hello Just wondering any idea which structure (in the image attached) has higher thermal stresses due to temperature change? Thankshttps://files.engineering.com/getfile.aspx?folder=77de0603-dcbe-4072-8284-c8953b80d49c&file=beam.jpg

Hello What would happen (stability/convergence/computational cost)if we use: 1) large time steps for explicit approach 2) small time step for implicit approach Thanks

Does anyone know how to apply ovality on a cylinder? I want to analyze a cylinder with X percent of ovality. Thanks

Hello I have a multilayer created with shell composite. The first and second sections are the same except section 1 has rebar layers. When I do "Render Shell Thickness" I see that for the rebar section, the thickness is much lower. I don't understand why? Is it due to the rebar layer? if so...

Hello In result/section point I see the following: Could someone explain how hey are defined? There are 4 layers. How can I know what is layer 1,2, or 4? Please see the image in the link. Thanks https://files.engineering.com/getfile.aspx?folder=6451b069-1397-4c17-b56e-ee0ed87ebee1&file=Capture.PNG

Hello I am trying to extrude a projected sketch (circle) on a cylinder. How can I do that? Thanks

Hello 1) What does S11 (Not longitudinal in my case) stress mean for a cylinder? Does It mean principal stress along x direction? or It mean like circumferential principal stress? 2) In my result, the von Mises is less than the yield stress but S11 is bigger than yield stress and I see some...

Hello When I want to mesh a part in Abaqus, It says: Environment Error: An Error has occurred loading the excel utilities plug in. The modulus pythoncm, win32com win31api are required. Any one knows how to resolve this error?

Hello When I want to run the model after a few seconds I get this error "Error: Check the disk space on your system, An attempt to access admc buffer has failed" but I see I do have enough space. Any suggestion how to solve it?
