Dear all,

         I am new to X-FEM, started reading papers a couple of weeks before. I understood, functions[heaviside,sign..] are used to enrich the nodes to simulate virtually the discontinuity and asymptotic functions are used to charecterize the crack tip,other than this regular FEM nodes are there. I have few questions. 

The Adhesion Society will hold its 32nd Annual Meeting in Savannah, GA February 15-18, 2009; uniting chemists, physicists, mechanists, engineers, and biologists concerned with the design and characterization of materials interfaces and their associated property of adhesion.  Adhesion and interfacial constrol are key to the development of nano- and bio- based technologies as well structural and cosmetic applications that influence society in everyday life.

For outstanding contributions to the mechanics of active materials

I have been told about "Spin Softening" option for rotating cylinders in Ansys but did not really understand how/what/why. I have gone thru Ansys documentation and it appears that the centrifugal loads are applied to the deformed configuration if the Spin Softening option is selected. Does Abaqus have a similar option ?

Now what the "Spin Softening" is meant to do is apply a centrifugal force:

F(r) = density*(r+u)*speed^2

Post-Doctoral Fellowship: Looking for energetic researchers with strong background in constitutive modeling or multiscale material simulations. Specialty on fatigue and fracture of metals, polymer or short fiber composites is a plus.  The primary research will be focused on physics-based damage, fracture, and fatigue modeling and simulations at various scales.  If interested, please contact Dr. Yibin Xue via email or visit her website.

I post some (hand-written) notes on compatibility conditions for both small and finite strains that I have used for helping me in lecturing. These may be useful for our student friends on imechanica. I also post a paper on compatibility conditions for the Left Cauchy-Green field in three dimensions as well as the paper by Janet Blume on the same subject.
