In this paper we propose diff erent 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 eff ective Poisson's ratio equal to zero. The connection between microstructural parameters and eff ective properties is shown in detail both analytically and numerically.
Continuous system with null Poisson's ratio:
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
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
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.
Giacomo
