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.
There is an open
position at the Institute of Applied Mechanics of the Clausthal University of
Technology (Germany) for a
Research Assistant or PostDoc
(TVL-E13 full time position, for 2 years).
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.
The assignment:Determination of crack propogation direction for CT specimen using different theories such as MTS,MTPS,Del-criteria,T-criteria,Ip theory
using ansys multiphysics
1) What are the boundry condition to be used for above criteria
2) How to take care of mixed mode loading
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.
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
