plane stress incompressible neo-Hookean hyperelasticity

Submitted by SAMICORP on Tue, 12/13/2016 - 15:20

Hello,

I was wondering how is it possible to implement incompressible neohookean material in abaqus?

With the incompressibility assumption c(3,3)=1/(- c(1,2)^2 + c11*c22), with c being the Cauchy-Green strain tensor. It also implies that S33=0 and it is possible to find the pressure directly. In addition, h=sqrt(c(3,3))*h0 with h and h0 being current and initial thickness, respectively.

my question is that how is it possible to implement the last condition in umat?

We would be hard-pressed to find an area of research that permeates so deeply in nearly all branches of physical sciences and mathematics as does the topic of homogenization [1].
