Continuous and discrete microstructured materials with null Poisson's ratio

In this paper we propose different classes of isotropic microstructured media with tunable Poisson's ratio. The elastic periodic systems are continuous porous media and two- and three-dimensional lattices. The microstructural parameters can be tuned in order to have an effective Poisson's ratio equal to zero. The connection between microstructural parameters and effective properties is shown in detail both analytically and numerically.

PhD Studentship in Computational Mechanics of Porous Metallic Materials

We are offering the PhD studentship at the
University of Surrey, and we are looking for enthusiastic and self-motivated candidates.

This project focuses on applications of metallic foams where structural functionality is combined with energy absorption, damping, heat insulation, and noise silencing.

Hi friends

how can i define  solids porosity in abaqus

for example i want simulate a plate with 90% porousity that in under tension

 

thanks

Journal Club Theme of December 2011: Mechanics of Porous Materials

Porous materials can be created by a variety of methods and exhibit properties that are advantageous in certain applications, e.g. insulation, energy absorption, and core materials in sandwich panels. As the length scale of the pores/ligaments is reduced below one micron, size effects arise and cause changes in the deformation mechanisms that operate in the ligament material. The mechanical properties can change dramatically, especially for so-called “nanoporous metals”, which have pores and ligaments as small as a few nanometers.

Dear colleagues,

We are very pleased to announce the Symposium

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

Which program? ABAQUS, Comsol or Ansys

Hi all,

I am a PhD student at the first months. I have to choose a finite element software to study impact effect on biological soft tissues. After some web researches the softwares which seem to be more suitable are ABAQUS, Comsol Multiphisics and Ansys.
My intention is to develop an user defined material model considering the material as anisotropic porous-visco-elastic.
I would appreciate some suggestions/opinion. I am specially interested in dynamical simulations.

Mechanics of porous material

Hi all,

I am going simulate a plate of porous material (SiC) to evaluate its strengh.

Would someone share some knowledge on the mechanics of the porous materials.

Thanks.

  Dear everyone

cellular/ porous material simulation software

hi - i'm new to the site and not familiar with material science in particular, however i'm currently looking for some simulation-software for cellular solids/ porous materials/ foam which allows me to evaluate the differentiation of geometry without too much scripting/programming - could anyone please point me in the direction of software available at a reasonable price (as an academic/student licence)/shareware/freeware which has output formats such as STL (Stereolithography), OBJ, DXF, IGES ..

Many Thanks!
