Different results when *DEFORMATION PLASTICITY vs *PLASTIC used for modelling plasticity of ductile meals in ABAQUS?

I got different results for a tensile test simulation when I used *DEFORMATION PLASTICITY (DP), instead of *PLASTIC (P) to model the same material. Ramberg-Osgood (R-O) parameters were directly provided for DP model while true stress/plastic strain values were calculated using the same R-O parameters for P model. Could somebody provide some insight into why that happened? This is not a fracture problem.

Large Deformation - Definition of total work energy density

Like we have the elastic strain energy density for small deformations  defined as 0.5* σ :e  .

Is the equation PK2:E valid for the total work energy density for elastoplastic regimes ? If not, what would be a valid equation for total energy density ?

How can we decompose total work density into elastic work and plastic work densities for a large deformation case.

Where,

PK2 is the second piola kirchoff stress tensor

E is the Green-Lagrange strain tensor

 

Thanks,

Prithivi

Why Abaqus give incorrect result in plane strain plasticity?!!

There is an incorrect result from Abaqus in plane strain plasticity simulation. In this short video, this  result is shown.

It would be pleased if anybody have any idea about why this happen ?!!

Hello everyone,

 

I'm last year PhD student. I would appreciate if someone could advice me about active research groups in Computational Plasticity (material models, hardening models, yield criteria, UMAT) in California or Australia.

 

I'm looking for an interesting research group to find a post-doc but I don't know from where start.

 

Thansks to everyone!!
