How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...

Please explain how the plastic input value should be considered from the true stress-strain curve for the bilinear elastoplastic material model ?

I am working on Abaqus/Explicit(Quasistatic ) for the deformation of the auxetic structure model. Please explain how the plastic input value should be considered from the true stress-strain curve...

What could be the possible reason that sintering of polycrystalline diamond fabricated with tape casting has suddenly started failing?

I make polycrystalline diamond with tape casting followed by HPHT sintering. When i sintered the samples up till May, the sintering was good. When i sintered the samples in June and July at the...

How to solve "1 elements have missing property definitions" in Abaqus?

I am creating a single element model in Abaqus of a composite material. My goal is to match the stress-strain curve of the material which was obtained experimentally. I am using VUMAT for Fabric...

What is the difference between creep deformation and stress relaxation ?

I understand the basic definition for both. I found a literature to describe both of them. In the paper, they states: If a stress is applied to a concrete body, the body experiences an elastic...
