    How to know which material model to use in ABAQUS

    @FEA way What kind of physical tests for hyperelastic materials are usually done?

    How to know which material model to use in ABAQUS

    what kind of test data?

    How to know which material model to use in ABAQUS

    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.

    crack during assembly in ABAQUS

    @FEA way But with this method, I think we already know at which stress cracks initiate right? If yes, that's not what I want. I want a design direction at the onset of crack. @SWcomposites Do you have any references or links?

    crack during assembly in ABAQUS

    Thanks, I don't want to have a real crack in my model. Regarding progressive damage and element deletion, how does that work in ABAQUS? Is there an option in ABAQUS?

    crack during assembly in ABAQUS

    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.

    Named selection

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

    extrude in Ansys 2022

    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

    Contact types

    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?

    Number of integration points

    @FEA way So can we say Its like mesh sensitivity analysis so we increase it until stress results don't change anymore?

    Number of integration points

    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 only support translation DOF but not rotation

    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

    How to delete node set?

    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?

    Shape function

    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

    Plastic strain tensor

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

    close thin wall beam vs open thin wall beam

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

    Big time steps for Explicit/small time steps for Implict

    @Mustaine3 Can we say something about convergence? using small or big time step has anything to do with convergence or it's all about stability?

    Thermal stress in multilayer reinforced composite beams

    @SWComposites; Why the left two? Assume same materials for each layer and a material with a bit elastic modulus higher for the fibers
