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}?

Hi all ... can somebody suggest me good book(s) on plate/beam theroy? The book should start for a novice and should go till large deformation part. Step by step explanation atleast for first few chapters should be there. Thank you.

Hello, I am trying to model a steel beam subjected to elevated temperatures using the ISO834 curve.

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!

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.

I am  searching the paper "Evaluation of stress distribution in the symmetrical neck of flat tensile bars" of J. Aronofsky published at Journal of Applied Mechanics (1951).
