Post-doc Position in Atomistic Modeling at Rice University

Submitted by Rouzbeh1 on

A postdoctoral associate position is available at Rice University in the

area of atomistic and molecular modeling of nanoscale friction and defects in an assembly of

nanoparticles. Computational techniques will be integrated to approaches from statistical

mechanics and physical chemistry to provide quantitative predictions of properties of complex

oxide materials across different time- and length-scales. The research will be carried out at Rice

University's Multiscale Materials Modeling Lab.

How to explain the coefficient of Hill 48 yield criterion?

Submitted by Weijie Liu on

Can someone help me to explain the derivation of the coefficent ?

 

 In the paper "A theory of the yielding and plastic flow of anisotropic metals", the Hill 48 yield criterion:

  

 

The quadratic Hill yield criterion for thin rolled plates (plane stress conditions) can be expressed as: 

 

However,  in the book of "塑性・粘弾性" link: http://www.worldcat.org/title/sosei-nendansei/oclc/047515845

Plotting stress vs strain curve in abaqus

Submitted by shafquatcd on

Dear All, 

 I am modelling a bridge rubber bearing using hyperelastic material (Rubber) and steel plates in abaqus. i am using mooney-rivlin hyperelastic model for rubber 

After running the analysis . i like to plot the stress vs strain graph for the rubber material only and then compare it with the mooney rivlin model .can anyone tell me how to do it ? 

 I am very new

Interactions between bone cells and their vicinity

Submitted by naili on

The aim of this project is to combine computing and experimental methods to improve our

knowledge in the bone cells interactions with their environment in the context of bone

remodelling. Indeed, bone cells are able to sense their environment and then to adapt

themselves. In this project three main avenues of researches are proposed: i/ to study the mass

transport phenomena in the vicinity of bone cells, that is to say within the pericellular matrix; ii/

About constutive relation of elastic membranes

Submitted by souvenir on

Is there some theory to describe the constitutive relation of elastic membranes?There are lots of papers studying membranes mechanics of cells, but I just want to know the mechanics of ordinary membranes which are simplified from theories of plates and shells, can anyone tell me some papers or textbooks studying this?(I've found a brief description on Allan Bower's web page, but that's too brief...)
