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

Free Tags:

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.

## Seeking a PostDoc position in field of mechanics of advanced materials

Dear All,

I got my PhD degree of Mechanical Engineering on Sep 2016 and I am seeking PostDoc position at well-known Universitiy or research Institute. Also, I completed my short-term visiting scholar at Purdue University on March 2016.

## Large Deformation - Definition of total work energy density

Choose a channel featured in the header of iMechanica:

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

## Modeling of Localized Inelastic Deformation 2016 (LID 2016)

Dear colleagues,

on behalf of the course organizer, I would like to bring to your attention to the advanced course on Modeling of localized inelastic deformation that will be taught by Milan Jirásek in Prague, Czech Republic on 19-23 September 2016.

## Please suggest self study book for continuum plasticity theory

Hello, I am new to theory of plasicity and need to learn it by myself. Please suggest a good book for self study for continuum plasticity theory. I am specially interested in metal plasticity theories, in analytical and numerical aspects.

## 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 ?!!

## Active Research groups in Computational Plasticity

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!!
