Summary:
I am thinking of informally conducting a specific case-study concerning the FEA solvers. The reference problem is a very simple but typical problem from stress analysis, leading of course to the linear systems: Ax = b and Ax = Lx.
I seek advice as to what software libraries currently available in the public domain would be best to use---the ones that would be fastest in terms of execution time for the reference problem.
Hi,
I am new to Abaqus and I am trying to use it to model some industrial shells. According to some preliminar studies, the material has a mohr-coulomb plastic behaviour. Thus, I wanted to use shell elements, with a mohr-coulomb plastic material, but it seems that it is not possible in Abaqus.
According to the theoretical manual and the user manual (18.3.3-6):
Does anyone knows what's the theory of the element shell99 in Ansys? I tried to search in ANSYS Help, but didn't find anything. Is it kirchoff classical plates theory?
I have a doubt regarding the next situation: I'm using a 2D shell deformable part with a solid homogeneous section (plane stress/strain thickness ratio=100) in a standard analysis (static general/static Riks). Should be in this case my mesh always bigger or equal to 100?
Is the plane stress/strain thickness ratio size influencing the minimum finite element size in ABAQUS?
How to connect a beam to a shell element in FEM and a shell to a solid? All the three differ in their dof's.
