I am currently working on a project on local nonlinear effects. Comfortably solved the problem using harmonic balance method. Then I move on to write my own code based on Newton Raphson method. Tried various suggestion and nothing sort out. If any one have the algorithm for modal analysis of nonlinear structures using Newton Raphson please share. Most code i found online are for nonlinear modal analysis, having nonlinear eigenvalue and not for nonlinear systems.
Thanks
