sorting single best data from different datas generated at same node

May somebody help me out sorting out a single value from four different values generated from field output to plot reaction graphs suiting bearing failure mode of bolted joints.

Cam Follower Prototype- GIF File

Submitted by Jigar Y. Patel on Tue, 02/05/2013 - 05:50

This is my cam follower prototype for clean energy cheaper than coal. Cam is used to open and close valve of internal combustion engine. I am going to show you another use. In my cam follower system,

1. Follower is off set.

2. Force is applied from follower to cam. Since the follower is off set this force help cam to rotate.

3. We use energy(Input energy) to move follower and get energy(output energy) on cam.

Compatibility equations

non-sinply-connected bodies

Compatibility equations of elasticity are almost 150 years old. Interestingly they do not seem to have been rigorously studied for non-simply-connected bodies to this date. In this paper we derive necessary and sufficient compatibility equations of nonlinear elasticity for arbitrary non-simply-connected bodies when the ambient space is Euclidean. For a non-simply-connected body, a measure of strain may not be compatible even if the standard compatibility equations ("bulk" compatibility equations) are satisfied.

Cyclic Hardening

Hi Everyone,

We are testing an AISI 304 SS Pin under cyclic loading and the results show that the buckling pressure would increase after exposing the pin to the cyclic loading for a while. I was wondering if this could be a results of cyclic hardening and if anyone has a link to some useful information on this case.

Thank you!

ALE adaptive meshing in abaqus used for modeling crack propagation

Submitted by A.Brick Chaouche on Sun, 01/27/2013 - 19:29

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
