ABAQUS and Sizes!!!1

Submitted by P M G B A on Mon, 03/09/2015 - 06:27

Hi everybody,

I want to model a biological cell, diameter of 10 microns! Then what should be the apporx. size in CAE? I am confused! I got to know that the minimum size of parts should be in mm, is this right. then how to solve the problem.

Thanks in advance

Professor Richard Christensen (Stanford University) published Part III of his series of papers on the failure theory. This is a short, but interesting view-point paper. The paper is attached (JAM, April issue, 2015).

Postdoctoral position at SISSA-International School for Advanced Studies

Submitted by Giovanni Noselli on Sun, 03/08/2015 - 11:58

A postdoctoral position is open at SISSA (http://www.sissa.it/) within the research group SISSA-mathLab (http://mathlab.sissa.it/). Prof. Antonio DeSimone (PI of the ERC Advanced Grant 340685-MicroMotility) is seeking a postdoctoral researcher to carry out an experimental activity focused on the study of low Reynolds number micro-swimmers. The postdoctoral researcher is expected to collaborate with other scientists of the group. A suitable candidate should have a strong background as an experimentalist.

Plane stress formulation of hyperelastic material

Submitted by afallah on Sat, 03/07/2015 - 07:38

I'm looking for good refrences for plane stress formluation of transvesrly isotropic hyperelastic materials (imcompressible). I'm wondering if someone help me and introduce some usefull material about it.

Kind Regards

I came across this very instructive article, so I decided to share it here.

Enjoy!

ABAQUS - Input file - Definition of nonlinear spring (SPRINGA)

nonlinear spring input file abaqus

Hello all,

I am currently working at a structural dynamic problem with Abaqus/Explicit. The work involves an impact and in this context the goal is to connect two rigid bodies (with their constraint, mass and velocity field) to each other with a NONLINEAR SPRING; the element used is the so called SPRINGA element.

Using File-->Import-->Model I have imported the input file, which I have previously modified in the following way:

*Spring, elset=SPRING-spring, nonlinear

dislocation dynamics

# Finite Element modeling

Semiconductors

Prof. Wei Cai at the Mechanical Engineering Department of Stanford University is seeking a postdoctoral researcher to lead a project on the modeling of dislocations in strained semiconductor structures. The major task of this project is the development of an interface between the Dislocation Dynamics program (ParaDiS) with a general purpose Finite Element Method (FEM) program (such as ABAQUS). Molecular dynamics simulations may be required to provide physical input to the Dislocation Dynamics model.
