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?
A new postdoctoral position in continuum mechanics is available at the Weizmann Institute of Science. Candidates should have a strong background in physics and/or theoretical mechanics, as well as experience with analytical and computational methods for solving partial differential equations. Possible projects include the mechanics of frictional sliding, the mechanics of biomaterials, the mechanics of glassy materials and dislocation-mediated plasticity. Highly motivated candidates are requested to send their CV, publications list and statement of research interests to Dr.
Hello colleagues.
I am solving a ring as an axisymmetric solid. I apply displacements and define reactions. According to an experimental data calculated reactions twice larger. We think it because the ring is thin and it is too rigid in solid formulation. Did anyone see solid formulation with a rotational DOF, i mean in any other FEA products?
This paper studies the poroelastic behavior of an alginate hydrogel by a combination of theory and experiment. The gel—covalently crosslinked, submerged in water and fully swollen—is suddenly compressed between two parallel plates. The gap between the plates is held constant subsequently, and the force on the plate relaxes while water in the gel migrates. This experiment is analyzed by using the theory of linear poroelasticity.
Hi all,
I am conducting some cohesive crack simulations within the framework of XFEM. The cohesive model is an initially rigid traction-separation law for mode I. In order to deal with negative values of the normal sepration/jump, I use a penalty stiffness K.
