Unit cell model

Submitted by Gouse on
research
unit cell
two phase

Hi,

I have modeled a two phase unit cell with one inclusion in a soft matrix. I have applied appropriate periodic boundary conditions. Load is applied a displacement. I have solved the problem using FEA through ABAQUS. Now I want macroscopic stress-strain response of the material.

What I have done is, taken the Reaction force and divided it by the area and similary displacement and didvided by length, will this give me the stress-strain response or do I have to use some homogenisation methods.

Thank You

Crystal Plasticity

Submitted by Mubeen on
research

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.

Abaqus CPT with cohesion.

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
research

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

Tiaxiality in unit cell calculation

Submitted by Mohamed H.Miloud on
research
micromechanics and cell calculation

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

about the multiscale aggregating method (MAD) of Prof. Belytschko

Submitted by phunguyen on

Hello all

I have spent a large amount of time trying to undertstand the multiscale aggregating method (MAD) of Prof. Belytschko. Unfortunately, I still can not compltely understand the method. 

If there is anyone here in the forum already gets clear about the method, please help me.
