abaqus software
dear friends
i want to model a spring with nonelinear plasticity behaviour in 3directions by abaqus to attach two or more parts together but I can not do it.

j integral and stress intensity factor relation
Hi,
Dear all,
We all know that J can be calculated by J=1/E(KI^2+KII^2).
but how to calculate the KI and KII from J.
I facing this pronlem as Abaqus can only calculated J integral for epfm, but I need the KI and KII as I only got K threshold and KIC for the material.
Thank You

Cohesive Element Tutorial
I am intending to carryout a Microbond single fibre pull-out simulation using abaqus. May someone please suggest to me a tutorial which uses cohesive element which I can follow as a guide to solving this problem?
Thank you.
PhD positions in Computational Mechanics at the University of Salento in Lecce, Italy
3 PhD positions are now available at the Department of Innovation Engineering at the University of Salento in Lecce, Italy. Funding is provided by the European Research Council Starting Researcher Grant project "INTERFACES-Mechanical Modeling of Interfaces in Advanced Materials and Structures".
The successful applicant will work on topics related to computational methods for interface modeling, isogeometric analysis, and multiscale methods.
Applicants should possess the following qualifications/attributes:
Postdoc in MD Simulations and Theory of NanoFriction (Erio Tosatti's Group, SISSA, Trieste)
Funded through SNF SINERGIA Project ‘Understanding nanofriction and dissipation across phase transitions’, we open in SISSA a postdoctoral position (‘assegno di ricerca’) in the area centered around nanoscale tribology (friction, dissipation, adhesion, wear) involving modeling, theory, and molecular dynamics computer simulations of nanofrictional and nonlinear dissipation phenomena, especially in presence of continuous phase transitions.
cutting simulation
hi,
i am doing cutting simulation, but not able to produe the chips i known the johnson-cook damage parameters and all the required parameters, i am confused with weather .inp file to run in ABAQUS/Standerd or Explicit,
[ABAQUS] Through-wall crack in a pipe
Hi iMechanicians,
Currently modelling pipes, I am trying to calculate J-integral for through-wall crack. I do not use XFEM method since it does not work very well with elastic-plastic materials then I use the classic approach and I must sketch a precise mesh around the crack tip, which is perpendicular to the external (and internal too) surfaceof the pipe.
Ansys help - simple flow rule analysis
Hi all.
I want to analyse a plate with a hole using ansys. But it has a material non-linearity. The stress strain law I want to use is σ = K εn
I want to know how it can be done. I've seen and tried ansys but it has options like kinematic hardening etc... but how to incorporate this relation...please guys it's urgent!!
Thanks.
Postdoc Position in Chile
The Superior Councils for Science and Technological Development of Chile will call for the FONDECYT Postdoctoral Grants Competition.
The available grants are for 2 or 3 years. The applicants must have obtained their Doctorate degrees between July 2009 and June 2012 (the exact dates will appear in the page of the agency later on).
