Dear all,

 Our paper titled "Cracking of the concrete cover due to reinforcement corrosion: A two-dimensional lattice model study"

 has just been published in Construction and Building Materials. It deals with numerical modelling of cracking of the concrete cover as a consequence of reinforcement corrosion, based on the Delft lattice model framework.

My name is hexu,a graduate, my major is solid mechanics,eapecially micromechanics,also study finite element method.

I am working on a dynamic post-buckling problem.

I wonder if it is possible to simulate dynamic post-buckling of a column with pinned-pinned boundary conditions with an time varying (sinusoidal) axial load in Abaqus.



Thanks.



Good day.

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

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

(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.
