I am currently working on this project. https://www.simscale.com/projects/esavli/nonlinear_sym4/
Basicly it is 1/4 a polyethylene corrugated pipe and i want to see the behaviour in large deformations. Also during tests i have deformation in square profile top of pipe. I want see as well but not at first sight.
I dont have yet plasticity spesification of PE, until this i am doing it as aliminum pipe.
My main problem is, i always have “singular matrix problem”. Probably have some problems in contact setup or boundary descriptions but somehow i could not figure it out.
