Incompressibility limit

Dear All,

I want to calculate  the limit of the fraction (J-1)/(1-2*nu) when material approach to incompressibility, where nu is the Poisson's ratio and J is the third invariant of the Cauchy-Green deformation tensor. In this case J->1 and nu->0.5, but I can't find any reference, how J depends on nu.

Intuitively, this limit has to be a finite value, as it is known that (J-1)^2/(1-2*nu) -> 0 (under the assumption that there is no hydrostatic pressure). Thanks in advance for any suggestions

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.

4th Canadian Conference on Nonlinear Solid Mechanics (Montreal, July 23-26, 2013) - Abstract submission deadline March 1, 2013

CanCNSM Conferences are intended to provide an international opportunity for communicating recent developments in various areas of nonlinear solid mechanics and materials. After 3 successful conferences in Victoria, Vancouver and Toronto, the 4th Canadian Conference on Nonlinear Solid Mechanics will be held in July 23-26, 2013 at McGill University which is best recognized for its research and discoveries in different fields of science.
