The Department of Industrial Engineering at the University of Pittsburgh anticipates an opening for a postdoctoral associate starting January 2012. The position’s primary area of research will focus on mechanics of micro-scale deformation processes and characterizing the thermomechanics of deformation at micrometer length-scales. Applicants with a strong background in computational solid mechanics and crystal plasticity will be preferred. 

Interested Applicants are requested to Email their CV to:  ravishm [at] pitt [dot] edu 

Dear My friends:

We recently published two papers that present an optimization method to design multi-layer composites with damping properties. The method consists in adding elastomeric layers in the composite. In this way, a multi-criteria optimization tool has been developed to determine the best geometrical and material properties of the composite: position of the elastomeric layers, layers thickness, ...

We develop a method of poroelastic relaxation indentation (PRI) to characterize thin layers of gels.  The solution to the time-dependent boundary-value problem is obtained in a remarkably simple form, so that the force-relaxation curve obtained by indenting a gel readily determines all the poroelastic constants of the gel—the shear modulus, Poisson’s ratio, and the effective diffusivity.  The method is demonstrated with a layer of polydimethylsiloxane immersed in heptane.

hi I am a student of mechanical engineering, Isfahan university of technology in master degree and the title of my thesis is:Rapid crack propagation in pressurized pipe

in order to use Abaqus X-fem for simulation of cracked pipe I have some essential questions :

1)Can I simulate rapid crack propagation of this geometry in Xfem? (with attention to the geometry of a pipe)

2)Is Xfem able to analyze Ductile fracture?

3)Is Xfem able to use larg deformation theory?

Dear colleague,   

The fourth issue in 2011 (Volume 24, Issue 4) of Acta Mechanica Solida Sinica (AMSS) is now online. 

Welcome to this SCI-indexed journal <http://ees.elsevier.com/camss/&gt; for rapid publication of your exciting results.

All models are wrong, but some are useful. This famous saying mirrors the situation in cell mechanics as well. It looks like no particular model of the cell deformability can be unconditionally preferred over others and different models reveal different aspects of the mechanical behavior of living cells. The purpose of the present work is to discuss the so-called tensegrity models of the cell cytoskeleton. It seems that the role of the cytoskeleton in the overall mechanical response of the cell was not appreciated until Donald Ingber put a strong emphasis on it.
