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.
Microindentation hardness mapping has been widely used to assess the variation of mechanical properties across a large surface area. However, with the study of applications such as glass it is the crack initiation that is of particular interest. It is for this reason that acoustic emission can be used during the mapping of indents to not only map hardness but also map the crack initiation values over the surface area.
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?
Hello sir,
I'm working on high velocity impact analysis of solid particle
erosion, in which i have to simulate the impact of particle on the
target.
I modelled the target as rigid and the particle as bilinear kinematic mat model...
I gave initial velocity and acceleration for the particle.
The surface to surface automatic contact is used
3D element of soid 164(8 node hex elems) are used...
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/> 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.
hi,
I have to do stress relaxation of fabric under stress condition. For this I have assumed my fabric as orthotropic material.
I need to find a stress relaxation on fabric under stress condition. Can anyone suggest the procedure to solve this analysis in
ANSYS.
Thanks
