Crystal Plasticity

Submitted by Mubeen on

I am interested in the computational crystal plasticity (elastic-viscoplastic models), and I intend to start working in this area. Therefore, I am looking for some review papers--

1- which provide an overview of the state-of-art in this area (a summary of the recognised single crystal plasticity models).

2- about the application of single crystal plasticity using micromechanics based  multiscale FEM for the prediction of texture evolution.

--------

I will be very thankful if sombody can answer these queries.

Abaqus CPT with cohesion.

Submitted by incarnation.adi on

Hi all...

I am new to abaqus. I have to model cone penetration test (CPT) in abaqus.

I am using drucker prager plasticity and hardening to model the soil.

The cohesion (d) decreases as plastic strain increases. But how do i input this into the model ?

Drucker prager hardening inputs have yield stress and plastic strain columns.

So from cohesion, how do i get the yield stress values ?

Obtaining Stress Triaxiality in ABAQUS

Submitted by unsrohith on

Hi ,

     The latest versions of ABAQUS (6.8 & 6.9) gives an option to obtain the stress triaxiality at the element integration point with the input file command TRIAX. Does any one tried to use this? I used this in my input file but unable to find the respective variable in the .odb file to plot the Triaxiality contour.

 Thanks and Regards,

Rohith

ENTROPY

Submitted by Rajdeep P Rajput on

I want to what exactly entropy means???I know the definition and formula but still not getting the physical significance.When we say temperature we can understand and feel it.But,in case of entropy each time I read about it I don't get it.Can anybody explore it's significance in easy way so that i can understand what exactly entropy means?

Tiaxiality in unit cell calculation

Submitted by Mohamed H.Miloud on

Dear imechanica Members,

I want to make a comparison between the results of a calculation of unit cell model and Gurson but I have a little problem on the triaxiality.
How to use the Riks algorithm in AbaqusCAE that the triaxiality remains constant during the loading of a unit cell?
Thank you for your help.
Best regards
