Abaqus / polymer simulation

Submitted by poucinette on
Hi all,



I'm trying to model a peel T test on a composite material composed of steel and polymer (polypropylen) on Abaqus 6.7. Between these parts, there are cohesive elements COH3D8.

I have a problem with my model and I don't understand it. You can visualize my results in attachs files.

For understand this draw, a few precisions:

The elements in white has just here to guide the materials.

In B (cf attachs files), the nodes are embedded.

In A I applied a velocity.

Call for Papers: Multiscale Modeling and Simulation: from Molecules to Cells to Organisms

Submitted by jcliao on

Dear Colleague,



We want to draw your attention to and encourage your participation in a special session on Multiscale Modeling and Simulation of the thirteenth Pacific Symposium on Biocomputing (PSB), to be held January 4-8, 2008, on the Big Island of Hawaii. PSB is an international, multidisciplinary conference with high impact on the theory and application of computational methods in problems of biological significance. 



crack instabilities around tips in Molecular Modellings

Considering the MD (molecualr dynamics) simulation programs, they enable us to define the initial crack and then using different theories they propagate the crack. This process is actually a dynamic feature at least when the sample is going to fail. Here is the question that present in the most modellers assumptions, which will limit the simulation or maybe it is not possible to simulate the process with out these assumptions. One of them which I would like to know your ideas about is the linear velocity which come into conclusions before the simulations start.

New Book: Computer Simulations of Dislocations, by Vasily V. Bulatov and Wei Cai

Submitted by Cai Wei on

Companion web site http://micro.stanford.edu ISBN:0-19-852614-8, Hard cover, 304 pages, Nov. 2006, US $74.50.

This book presents a broad collection of models and computational methods - from atomistic to continuum - applied to crystal dislocations. Its purpose is to help students and researchers in computational materials sciences to acquire practical knowledge of relevant simulation methods. Because their behavior spans multiple length and time scales, crystal dislocations present a common ground for an in-depth discussion of a variety of computational approaches, including their relative strengths, weaknesses and inter-connections. The details of the covered methods are presented in the form of "numerical recipes" and illustrated by case studies. A suite of simulation codes and data files is made available on the book's website to help the reader "to learn-by-doing" through solving the exercise problems offered in the book. This book is part of an Oxford Series on Materials Modelling.
