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

INRIA (the French national institute for research in computer science and control) has currently eight centres, and the Opale Project-Team is primarily located in the Sophia Antipolis Centre, near the city of Antibes. Our research focuses on functional and numerical analysis, and numerical simulation, with a special emphasis on optimization in science and engineering (compressible aerodynamics, electromagnetics, structural design, etc) with strong links with industry.

For lasting contributions to mechanics, and for building bridges between disciplines and between nations

An Immediate vacancy exists for high calibre  postdoctoral fellows with interest in multiscale computational nanomechanics, nano-modified composites,  testing and validation. Specifically, we are interested in determining the influence of nanofillers on polymer composites. Candidates should expect excellent facilities, good salaries and exceptional working conditions.

On behalf of Imperial College Press, World Scientific Publishing Co. (Singapore) and the International Journal of Applied Mechanics (IJAM), I would like to invite you to submit an article for our forthcoming journal, which will be launched in March 2009.  Given your expertise in Mechanics, your contribution to the inaugural issues of IJAM would be most desirable in our effort to make IJAM a leading journal in its subject area.
