meshfree shape function

Submitted by jeetender sing… on Wed, 02/16/2011 - 16:44

This is regarding the MLS shape functions, used in meshfree methods. How the number of sampling point affects the plot of shape functions for the nodes? Is the "peak values" fall down as the sampling points are increased?

ADINA Electromagnetics

Submitted by ADINA Support on Tue, 02/15/2011 - 15:01

We have recently added the ADINA Electromagnetics module (ADINA-EM) to our wide range of multiphysics offerings. Using this module, the general Maxwell's equations can be effectively solved and the resulting electric and magnetic fields can be coupled to the fluid flow. For details please see:

clifford algebra

Every year I try to get funding for things that I'm personally interested in but which may not have any immediate economic benefits. A couple of years ago, after reading Penrose's "Road to Reality", I thought about applying Clifford algebra ideas to fracture mechanics and wrote up a proposal to that effect. The proposal wasn't funded, but I think the idea is worth exploring.

The summary of the proposal was

cyclic loading

Hi,

I d like to ask you how could fatigue loading be modelled in cae. I know that you can set up the load as a sin function with min and max values. But where do you set-up the total nr of cycles? Is at the step part and where exactly?

And another question could anyone provide me with details of the input file for the hysteresis loop, where the stess nd strain resistance of the material drops after certain cycles..

Regards,

Panos
