Hello All!!!

 I am Arun, Master degree student in South Korea.

 My research field is : High strain rate experiemnts

 I did High speed tensile test for aluminium alloy at four different speeds (1m/s, 5m/s, 10m/s and 15m/s)

 I also did high temp tensile test for aluminium alloy at room temperature, 100 C, 250C

 Now i have the stress Vs Strain curve for High speed tensile test and high temperature test

 But, i don't know how to determine Johnson-Cook model parameter from the experimental results

Dear Colleagues,

We are pleased to inform that the abstract submission deadline for the 23rd International Workshop on Computational Mechanics of Materials (IWCMM23) has been extended until May 31, 2013. The conference will be held in Singapore during October 2-5, 2013. 

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.

Best Regards,

Rajnish

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

Technology (Germany) for a
