Baushinger's effect
Hi friends,
Can you explain Baushinger effect?
how it is related with KINEMATIC HARDENING?
Thank you

2D Contact Problem In AINDA84
ADINA84 is an open source code which can solve contact problem.
My model is shown in the picture below：
Pipeline and seabed are both 2D 2-node beam element and seabed is rigid surface.
I define one contact pair,two contact surface and each surface has 99 nodes .Two surface's nodes have same coordinate.
The program'erro is"CONDITIONS OF CONTACT INADMISSIBLE DUE TO DETECTION OF GROSS OVERLAP".
Who can tell me the reason？
Several questions for VUMAT
Hi all, I am a new ABAQUS VUMAT user. I am defining the material behavior in stamping of sheet metal through VUMAT. But there are several questions about VUMAT.
（1）accoring to the ABAQUS user manual，for plane stress problem，stressnew(nblock,ndir+nshr), where ndir=3,nshr=1, but in fact,there are 5 stress commponents: sigma_{11},sigma_{22},sigma_{12},sigma_{23},sigma_{31}.
how to match stressnew(*,i)(i=1,2,3,4) with the stress commponents: sigma_{11},sigma_{22},sigma_{12},sigma_{23},sigma_{31}?

Abaqus Help Needed for heat analysis in beams
Hello, I am trying to model a steel beam subjected to elevated temperatures using the ISO834 curve.
Wave-Structure-Foundation interaction (Fluid-Str-Porous Media int.)
Dear all,
can anyone direct me to litrature in which modelling the diffusion equation of fluid porous flow is unified with the free fluid flow. I mean that the porous media is considered deformable and equilibrium conditions are solved simultanouesly with diffusion eq. for porous flow and at the same time fluid velocities inside and outside porous media are linked together in a poroelastoplatic framework; where porosity and geometry are updated with each time step!
Thank you in advance!

Finite Element Method.
Hello,
I would like to develop a Program for finding the Stiffness of a stabilizer bar using FE methods.
I have a fairly good idea about FE methods as to how to proceed but the books i referred to mostly dealt with symmetric solids.
Can someone throw light on FE procedure for such component with a complicated shape(or some books that deal with 3D assymmetric solids)..??
Thanks.
