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.

Materialise and Dassault Systemes Simulia Benelux are pleased to announce their co-organized Medical Engineering Seminar which will take place on 4 October 2011, at the Materialise HQ in Leuven, Belgium. The Medical Engineering Seminar is a meeting for and by users and aims to bring together biomechanical engineers currently working, or interested in patient-realistic finite element modeling.

It is pleasure to announce that there is an
opening for students who want to join a PhD course or combined master + PhD
course (Going to directly Ph.D. course without master thesis after B.S.) in
Department of Aerospace Engineering, GyeongsangNational University, South
Korea.

The successful candidate will do research
under the advise of Prof. Jin-Hwe Kweon in Structures and Composites Lab. Research areas include testing and finite element analysis of:

Hello,

Im trying to simlate delamination in abaqus and after going through the documentation i decided to go for the cohesive element approac. In the documentation it is mentioned that we use a general contact(explicit) for the interation but when i do that i am unable to use general, static step. So which step do i go for if i i want to simulate a static delamination ?

I am looking for a post-doctoral fellow and two PhD students. The research projects are concerned with electromechanical performance of PZT actuators in hydrogen-based fuel injectors (PDF), modeling of fuel cell membrane durability (one PhD) and nanoscale mechanics (one PhD). Interested applicants are asked to send their CV and transcripts to: Dr. Nimal Rajapakse, Dean, Faculty of Applied Sciences, Simon Fraser University, Burnaby, Canada.
