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.)

Submitted by Anonymous (not verified) on Mon, 07/26/2010 - 16:54

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!

Recently I have some reseach on z-pinned composite. I hope use finite element method to analyse the unit cell . I found a FE code called FLASH mentioned in many papers. I think the code will be helpful to my work.But I can not got the code form my resource. So,I ask help in the forum. Two papers about the code are given in below. I am very expect for your help!!!

Finite Element Method.

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.

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).

Hello
Everybody,

I’m using
Prony series to model viscoelasticity of an asphalt material in a pavement. I
have defined the material properties through time-domain Prony series in
Abaqus. The parameters are:

g_i (shear
relaxation modulus ratio): 0.8

k_i (bulk
relaxation modulus ratio): 0

tau_i
(relaxation time): 1

Dear All,

I would like to announce a symposium in memory of Pr. Olivier Coussy

Mechanics and Physics of Porous Solids : a tribute to Pr. Olivier Coussy

It will be held at Ecole des Ponts ParisTech, France from 18 to 20 April 2011.

All informations can be found in the ongoing website http://navier.enpc.fr/events/mpps2011
