Fabric Tensor

Submitted by gyanvikash on
research

I am studying the effect of intermediate microfabric on clay's mechanical behavior. In order to develope the constitutive model for clay considering its microfabric, I want to use fabric tensor. If any good paper or study material on fabric tensor is available then please send me.

Thanks

question about abaqus

Hi guys

I want to simulate a problem with abaqus,but during runing of my project,percent of process not increas for axample when i change mesh sizes to biger runing go up to 50 % and when i change mesh sizes to smaller than the previos size,it occure again but in 25%

is there any one that know about this problem,i'm trying to solve it for 2weeks but i cann't.

I'm waiting for your suggestions...

I found the below thread, and thought this would be a good place to ask about open source FEM.

But unlike that thread, I want something that is very simple, that can be run with just a single .exe.  I only need to solve basic structural problems and perhaps eigenvalue problems.  Orthotropic material capability is needed, but input for a composite material via lamina and stacking sequence would be better.

Abaqus UMAT problem

Hello

I'm a new commer in Abaqus and working on topology shape optimization for dental implantation.
I have two user-defined materials for Jaw bone area, and using the stress-increment-controlled method
Young's modulus of an element is changed according to the following equation (1) with two constraints (2)

E(i+1) = E(i) + k(sigma(i) - sigma_ref)   --- (1)

where k and sigma_ref are constants

E(i+1) = E_min if E(i+1)<E_min

The group of Mechanics of Solids and Structures at the  University of

Brescia is seeking two candidates for Ph.D. positions. The appointment

is starting on January 1st 2011, application deadline Sept. 15th 2010.



The research topics involve: computational dynamics of solids with

reference to ground motion simulation due to seismic input, multiscale

computational fracture mechanics and discrete dislocation mechanics.
