Damping of multi-layer composites
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, ...

Poroelastic relaxation indentation of thin layers of gels
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
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
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
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...
