PATRAN boundary conditions

Submitted by Peter M on Sun, 04/21/2013 - 09:47

Hi,

I would ask if someone could help me. I'm trying to aplly rotational boundary conditions on a cylinder in MSC.Patran, could someone advice me how to do it? Thanks a lot

multi-surface plasticity

Dear all!

For quite a long time (not full time though) I've been trying to get a multi-surface plasticity model running, without finally successing. Yet.

I am coding the algorithm Simo & Hughes give in "Computational Inelasticity" in Box 5.2a-c into an Abaqus-umat written in fortran. I apply it for perfect plasticity (at the moment), therefore it is simplified from the original.

Stress calculation after simulation

Stress and Strain Calculations

Average volume

Nodal force methods

I am working on reinforced fiber composites, after modelling the unit cell(R.V.E) of the composite various boundary conditions are applied. After this result is obtained. The results are element(elements produced after meshing)-oriented. I want the stress as a whole on the whole unit cell. I have tried measuring the forces on the faces by taking the cumalative of nodal forces on each face. However, the common edges creates a problem. Can you suggest any other methos of calculating the stress on whole body.

A PhD opportunity in the field of computational and applied mechanics is available in the department of Civil and Environmental engineering at the University of Illinois at Urbana-Champaign.

Qualifying candidates must have a strong background in mechanics and mathematics. Familiarity with scientific computing in one of the widely used programming languages (e.g. Fortran, C++ or Python)is required.

how to extract the story mass and story displacement in Abaqus?

Submitted by meshee on Fri, 04/19/2013 - 02:18

software

hello, everybody

I've made a 3D multi-story frame and shear-wall model in Abaqus. So far, I wanna get the equivalent story mass, story stiffness and story modal displacement. how to extract the story mass and story displacement in Abaqus? or how to make an equivalent multi-mass point system from original 3D multi-story model?

Thanks in advance

Best Regards,

Shelton
