Poroelastic relaxation indentation of thin layers of gels

Submitted by Yuhang Hu on

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 Mapping With Acoustic Emission On Glass

Submitted by NANOVEA on

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.

dynamic fracture with Xfem

Submitted by bijan.jamali on

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?

Impact Analysis using ANSYS/LS-DYNA

Submitted by balavenkatesh on

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...

On Tensegrity in Cell Mechanics

Submitted by Konstantin Volokh on

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 & Simulia Medical Engineering Seminar

Submitted by Mimics on

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.
