Dear All,
I modelled a beam with a hole and used cohesive elements on the possible crack plane.
When I run the model in 2D, it works very well and I can get the results pretty good.
Why running the same model in 3D (making 3D model and running it) has caused me a headach for a long time and I can not
get the results?
Any idea highly appreciated,
Thanks,
Parisa
i am simulating a uniaxial test for coal specimen using Mohr-Coloumb plasticity, there is a friction between the coal sample and the platens, the coal behavior is stain sotening.
i want to know how many points should i use in the hardening table of the mohr-coloumb plasticiy to get a good reults?
i used 3 points:- the first one is the yield stress and the associated plastic stain, the second one the peak stress and the associated plastic strain the third one is the post peak stress and the assoiacted plastic strain. is that right?

A Research and Development Scientist position in developing multiscale-multiphysics computational technologies for composite materials and structures is available immediately at the Multiscale Design Systems, LLC located in New York City. The candidate should hold a doctoral degree in a relevant discipline, such as Mechanical, Aerospace or Civil Engineering. The candidate should have a strong background in multiscale simulations and scientific programming (C, C++, or Fortran).
We have an opening for a postdoctoral scholar in the area of computational mechanics. Specific problems of interest include the nonlocal plasticity, molecular dynamics and meshless methods for continuum damage mechanics. Rich experience of C++, X-windows image processing, and Fortran programming (especially parallel processing) is required. Contact: Professor Jung W. Hong at Michigan State University.

Hi
I will model laminated composite and it have contact element at between layers. Can anybody help me for define of contact element(ANSYS) at between layers?
thank you
I'm simulating the interface between a steel plate and the fire proof coatings covering the steel plate. The elements i use in the simulation is contact 173 with a material property of debonding,which is defined as cohesive zone model.(CZM)
CZM in ansys provides TBDATA such as maximum contact stress,contact at the completion of debonding, but what's the problem is that I failed to set the initial contact stiffness. it's true that ansys provides FKN to define the contact stiffness, but it's just a stiffness factor.
Any idea why energy deviation between successive steps become a large value during molecular dynamics simulation, when the number of steps is increased?
