Hi:in a linear spring model for materials, the governing matrix equation is K * U = F
where K is the material stiffness AE/l , u is the displacement at each nodes and F is the force in the discretized elements.but this is only true for a linear spring, what if I have some non linear spring? I know there's no such thing but what if I now have some other physics that I would like to model that involves a non linear governing equation? how would I model my matrix?
thank you hihiip201
