Open source Matlab toolkit now includes 3-D beam elements

Submitted by Petr Krysl on Tue, 02/15/2011 - 01:39

The FAESOR toolkit now incorporates a linear and geometrically nonlinear formulation of three-dimensional beams. Some updates and fixes have also been posted.

Rodney Hill was born on 11 June 1921. He was a Reader, then Professor, in The Department of Applied Mathematics and Theoretical Physics (DAMTP), of The University of Cambridge, during the period 1969-1979. He is widely regarded as among the foremost contributors to the foundations of solid mechanics over the second half of the 20th century. He was author of 'The Mathematical Theory of Plasticity' published in 1950.

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

material parameters calibration for crystal plasticity

Submitted by Farahani1 on Sun, 02/13/2011 - 20:55

I am doing the crystal plasticity analysis of tensile test, at the first step in order to calibrate my model

I can use either force-displacemnt or stress-strain curve I was wondering which one is better to use, I am using abaqus-explicit

Fatigue

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

Extrude a solid section

Abaqus cae

Hi all,

I am having some troubles with the extrude command in Abaqus cae. I have modeled my sample as a 2-D geometry and now I want to move to 3-D for the same section. But I am having trouble extruding my 2-D section. It seems to me very weird and far to complicated the extrusion process in abaqus for such a simple task...

Thank you,

Panos
