Hi

I am working on large deflection analysis of a cantilever by finite element total lagrangian approach. the results for six element are reasonable but when I increase elemenets to nine solution is diverged. i.e. tangent stiffness matrix becomes singular. can anaone help me on this problem.

thanks in advance.

hello Dear friend

hello

my name is mohamad. I am phd student in mechanical engineering. I want to use of total lagrangian formulation for analysis of a cantilever. my difficulty is on implementation of newton raphson method and incrementing load. my code does not converge. can you help me. if there is a simple code I was wondering if someone aware me.

thanks in advance.
