Dear feusers,
I'm experiencing convergence problems with my implementation of an
incompressible NeoHooke material (actually I use this only to serve as a
ground matrix for a fiber reinforced material).
The incompressibility is satisfied using the terms K ( ln(J) )^2
withinin the potential (K is the bulk modulus and J is the volume
ratio).
Could anyone provide the sourcecode of a successfully implemented
NeoHooke material, please!
Yours, Mike
