question about "Extended Dracker Prager plasticity model"

Submitted by Gamal on

Hi my friends,

i am using Dracker Prager Plasticity model in abaqus 6.6, i am working on rock sample, this rock sample shows strain softening behavior not strain hardening, but you know that Drucker Prager can simulate both hardening and softening.

i have the stress-srain diagram from the laboratory test. 

 my shear criterion is linear, i choosed from Suboption   Drucker Prager Hardening.

Does anyone know how to keep a record of what you have done in a CAE session?

Abaqus CAE log file
In Abaqus/CAE, I get .cae file, but I want to teach someone else what I have done, step by step.
ANSYS keeps a log file that mimics exactly what you do in the ANSYS GUI, which is similar to CAE. 
How can I get CAE to write a log file with the steps that I did in the CAE session?

Requesting help on ALE and corpuscular method in simulating airbag in LS-DYNA

Submitted by Anonymous (not verified) on
education

Dear all,

 I am currently doing my undergraduate final year project on gas flow dynamics of airbag. I am using LS-Dyna to simulate 3 different gas flow condition (uniform pressure, ALE and corpuscular).

I am able to obtain a simple model of airbag from LS-Prepost website. I am modifying it to learn more on ALE and corpuscular.

For ALE method,

Homogenization in ABAQUS

Submitted by Svetlana Orlova on

Hello everybody,

I have a problem with homogenization of fibre reinforced composite in Abaqus.

I need to get stress components S11, S22, S33, S12, S13, S23 of each element and it's volume to calculate average stress on each element. Here comes the problem: I'm trying to use Field Output calculator but I can't multiply, for example, S11(i)*EVOL(i) because there are no components of S in this calculator and I can only operate with tensor S.
