Next CONTACT-course in december 2013
Dear all,
On Tuesday December 3rd to Thursday December 5th, 2013, we will organise a course on rolling contact mechanics using the CONTACT software at Delft University of Technology in the Netherlands.
The aims of the course are:
Frictional rolling contact model CONTACT version 13.1 released
Dear all,
Herewith I want to announce the release of the frictional rolling contact model CONTACT version 13.1.
The main changes with respect to earlier versions of the program are as follows:
Predictive abilities for stresses in individual inclusions and the matrix by the Mori-Tanaka and PGMT formulation
Both effective properties of composite and the stresses in the individual inclusions and in the matrix are necessary for modelling damage in short fibre composites. Mean field theorems are usually used to calculate the effective properties of composite materials, most common among them is the Mori–Tanaka formulation. Owing to occasional mathematical and physical admissibility problems with the Mori–Tanaka formulation, a pseudo-grain discretized Mori–Tanaka formulation (PGMT) was proposed in literature.
cost to measure residual stresses
Can please any one tell me about the cost to measure the residual stresses,in India
the process is:XRD
thickness is:10mm
Postdoctoral position at Texas A&M University in Qatar on modeling polycrystalline materials
One year postdoctoral position at Texas A&M University in Qatar is effective immediately; the work will be in the field of solid mechanics experimental investigation and modeling of Mg alloys.
One year postdoctoral position in solid mechanics effective immediately at Texas A&M University in Qatar at light material lab
This position is not located in the United States. Must be willing to relocate to Doha, Qatar.
What is incompressible solid?
Dear Colleagues,
In the literature two definitions of incompressible solid can be found. The first one is: Poisson's ratio =0.5, and the second is: the third invariant of the Cauchy-Green deformation tensor J=1. I wish to understand the connections between these two definitions. To me, here is something strange. Poisson's ratio relates strains to stresses,and J as the combination of strain tensor components, doesn't depend on Poisson's ratio. I'll be grateful to you, if you explain me how these two definitions are connected.
