Dear Friends and Colleagues,

On behalf of the co-organizers, I would like to invite you to submit an abstract to the symposium on Multiphysics Simulations and Experiments for Solids as part of the upcoming 2013 ASME IMECE conference to be held at San Diego, CA from November 15-21. This symposium is a continuation of the previous symposia that have been successfully organized in the previous ASME IMECE conferences. 

ALE adaptive meshing in abaqus used for modeling crack propagation

Submitted by A.Brick Chaouche on

Good mourning, i have been asking a question about Abaqus capabilities to model crack propagation using an adaptive remeshing technique on abaqus, i know it is possible to use what it is called ALE adaptive meshing on abaqus standard/explicit, is it possible to use this option to model a crack propagation in materials and structures, it is well know that during a monotonic crack propagation, each length of the crack correspond a level of load, and to evaluate the following parameters such as SIF and G, we have to mesh a circular region centred on the crack tip, so we have to remesh the Geom

Are Finite Element Softwares Reliable ?

Submitted by mohammedlamine on
research

Hello,

Some Finite Element Softwares use the Formulation of an Element and Jump to another one

by Merging Nodes : Quadrilateral to Triangular and Hexahedral to Tetrahedral without modifying

the Shape Functions.

This Method is Mathematically and Numericaly Forbidden because they use the Same Shape Functions

when Merging the Nodes for the Defined First Element (see Element Definition and after Mesh Process).

Piezoelectric composites

which element should i consider for the piezoelectric composite plate analysis in ansys. the lay up consists of top and bottom piezo layers and middle graphite epoxy? i want to apply sinusoidal voltage on top piezo layer and i need noidal deflections, please help in doing
