Can anyone plz send me instructions on how to calculate the coefficients a,b,c,d,h (f,g = 1)  for YLD91 and subsequent ones? I have a rough idea, but if someone has explicit instructions ..

I am glad to introduce VABS, a unique software tool for modeling of composite structures having one dimension much larger than the other two dimensions such as helicopter rotor blades, wind turbine blades, HALE wings, and bridges.

For fatigue life estimation (HCF & LCF), I am not sure which stress shall I consider i.e. max. principal stress or von Mises stress & what should be the criteria for selection of the same? Shall we be driven by material model (i.e. ductile or brittle) or mode of failure or some thing else?

A one-year Postdoctoral Research Associate position is immediately available for research on nanomechanical characterization and modeling of nanomaterials and biomaterials.

Hello! I am modelling crack propagation in concrete specimen under direct tension by using cohesive element in ABAQUS as the interface where crack will propagate. By setting up the proper values of the parameters, I could model the exact behavior prior to the cracking, however, when changing some parameters to get the interface cracked, the model committed to be diversed. I have tried some little skills like viscosity and energy disspation fraction, but it was still not working.

Highly qualified applicants are sought for two graduate research assistant positions in the areas of computational structural mechanics and design optimization.  The selected candidates will enroll in a PhD program in engineering and work with a team of researchers at the Center for Advanced Vehicular Systems (CAVS) in the Bagley College of Engineering at Mississippi State University.

We are now accepting abstracts on: 

• Mechanics of hard and soft biological materials
• Mechanics of biomimetic materials and systems
• Experimental methods applied to biological materials and systems
