Would like to hear your expertise/user/non-expert/sceptic comments on XFEM. Here are some of the challenges. Would like to hear your relections.

1. Can XFEM be utilized in characterizing Failure rather than Fracture?

2. What sort of challenges XFEM still have with respect to Fracture Mechanics?

3. How the Fracture mechanics benefit the industry, from the perspective of strcutural integrity?

4. Failue investigations vs. Fracture investigations: benefit to industry?

5. Academist vs Engineer: Perspective on XFEM

Hi,

 

For a personal project I'd like to find a free program that lets me see what happens when I take a beach ball and apply greater and greater weight on it.  I'm specifically interested in the deformation of the ball, and the stresses in the material.

 

Run ANSYS through MATLAB

Submitted by Maher Al-Dojayli on

Hello All,

Does anyone know if it is possible to run ANSYS as a solver through MATLAB ? I want to run optimization in MATLAB and change some variables whether they are geometry or material variables and run ANSYS through MATLAB to solve especially ANSYS CFX or Workbench where I can have multiphysics.

If this is possible, I would appreciate it if you can share the method of how to do so.

Thank you all

Maher

Finite Element Analysis of Vehicle and Tire has become a very important aspect of a tire design and failure analysis to most Tire companies. Tire modeling with ABAQUS is a very complicated process involving complex materials like hyperelastic rubber and textile reinforcements, large model size, prolonged simulation time and various convergence issues. This white paper intends to help in understanding the challenges in tire analysis and several tips and tricks that makes a difference in the quality of the results and processing time.

Multi time scale simulations for wear prediction in micro-gears

C/C++ codes to solve wear equation

Reliability of micro-gears is known to be adversely affected by wear. In this work we report a strategy to predict local wear with the aim of predicting their effective life span. For the prediction of local wear we start from the relevant model experiments, choice of a suitable wear model and identification of the wear coefficient from these experiments. This wear model is then implemented in an efficient finite element based scheme to predict local wear.

Finite Element Analysis of Thermo-Viscoelastic Problem

Hi,

 

I am trying to develop a finite element code to capture the residual stresses during the cooling of a viscoelastic body.

Can anyone suggest references or papers that address the finite element formulation of a thermoviscoelastic problem? I have found a couple of papers, but they do not seem to directly apply to what I want.

 



Thanks,
