The course covers the formulation of nonlinear equations of motion arising from geometric and material nonlinearities using the Principle of Virtual Work, along with the linearization of the problem. It describes nonlinear Newton–Raphson methods and presents applications to selected examples of nonlinear structural behavior. It also includes material nonlinearity, with applications to the elastoplastic stiffness matrices of isoparametric plane stress, beam, and shell elements.
