finite element modeling

electric vehicle

A postdoctoral research scientist position is available immediately in the Department of Earth and Environmental Engineering at Columbia University. This position is renewable (up to three years) depending on performance. The main responsibility of the project, sponsored by ARPA-E, is to perform computer simulations of crashworthiness of electric vehicles using finite element method. It also involves multiscale modeling of a new type of impact resistant lithium-ion battery, as well as structural design and optimization.

Incompressibility limit

incompressibility

poisson's ratio

Right Cauchy-Green Tensor

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
