In short explained: Linear and nonlinear structural analysis

2017-5-22  Nonlinear analysis. A nonlinear analysis is an analysis where a nonlinear relation holds between applied forces and displacements. Nonlinear effects can originate from geometrical nonlinearity’s (i.e. large deformations), material nonlinearity’s (i.e. elasto-plastic material), and contact. These effects result in a stiffness matrix which is ...
