Abaqus Damaged Plasticity- problem with Strain Rate

Submitted by Margi on
Forums
Ask iMechanica

Hi All,

I am using Abaqus explicit to simulate a simple compression test on a concrete cube. The cube's bottom face is fixed, and the compression is given by giving a displacement to the top face. In order to simulate concrete material I'm using the damaged plasticity model.

stress analysis

Hi All, thanks in advance for any replies.

I am currently doing my Thesis on fast stress analysis using the boundary element method and specifically, adaptive cross approximation. I ofter come across the terms "single layer potential" and "double layer potential", i "know" what they are mathematically, i was wondering if anyone could give me an insight into what they mean physically, or just give a simple non mathematical definition? Thanks a lot, Ian.

A challenge to Mr. Koenemann

I am sure that several of you have followed Mr. Koenemann's posts with some interests.  For some it might be entertainment, and for others it might be like watching a car wreck.  In any case, several iMechanicians have attempted to convince Falk that his theories do not make sense.  We have all failed miserably at that task.  I am perhaps a bit slower than most, but it is clear to me that Mr. Koenemann will not be convinced by any physical or mathematical arguments.

Beam analysis

Submitted by Anonymous (not verified) on

hi all,

 I am trying do analysis on a beam in ABAQUS which is coated with polymer meaterial and i have to test it in following conditions,

1. Humidity resistance: 50 ° C/85 ± 4% RH for 8 days

2.  Warm salt water: 58 ± 2° C/5% salt-water immersion for 8 days

can anyone tell me how to do this one...

Hi everyone,

Does anyone have the work experience on stepped column kind of structure?

I would like to know, how to determine the crippling load for stepped column kind of structures? If anyone have the materials pertaining to the subject, please do share (if interested).

 

Thanks and Regards

Fluid Structure Interaction

Hi every one,

 I am in my final stage of my dissertation, which is about slamming analysis of boat hulls with help of CEL - in Abaqus. I am currently working in how to validate the results which I got. Is there any way except experimental method to validate the stress - strain results?

Please help me...
