Fatigue

Submitted by Panos Efthymiadis on

Dear all,

       I would like to ask you, how is it possible to simulate fatigue in Abaqus. I have created my loading. But if I run it as it is it will never reach a critical value, so you could say there is no damage evolution. Is it the only way is to apply some type of hysteresis loop evolution and say that after some cycles the hysteresis loop changes?

Any advice is more than welcome!

Regards,

Unit cell modeling using Abaqus submodeling

Submitted by Gouse on

Hi,

I was going though papers related to micromechanical modeling of composites using unit cell approach. Usually in this procedure, a unit cell is isolated from the material and to ensure the compatabilty of the unit cell boundary, periodic boundary conditions are applied.

To ensure the compatabilty of the boundary and to apply loads, can we use submodeling techniques available in ABAQUS.

Thank you

Regards

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:

On proposals

Submitted by Biswajit Banerjee on

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

Fatigue

Submitted by Panos Efthymiadis on

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..
