NamHo Kim 1 Goals What is a nonlinear problem How is a nonlinear problem different from a linear one What types of nonlinearity exist How to understand stresses and strains How to formulate nonlinear problems. Nonlinear Model Problem Let us consider the nonlinear model problem 87228711 f in 8486 1a 0 on 8486 1b where is a given positive function depending on the unknown solution As usual is a given source function which we for simplicity assume not to BEAMS.
