Re: Nonlinear Elasticity (ICL=4, ITYCL=1)

Dear Alfonso, Thanks for your answer. It is very helpful. The convergence difficulties are also because I am modelling high thermal gradients under low overburden stress and net mean stress in the layers close to the surface tends to zero (and tension) quickly. As you explained, the formula doesn't ...

Nonlinear Elasticity (ICL=4, ITYCL=1)

Hello, I am using CODE_BRIGHT to model bentonite desiccation due to thermal gradients. I have used Nonlinear Elasticity (ICL=4, ITYCL=1) which gives reasonable results. However, I have convergence difficulties with high thermal gradients if P6, tension term to avoid tractions, is smaller than 0.2MPa...
