PPT-CHAP 3 FEA for Nonlinear Elastic Problems

NamHo Kim Introduction Linear systems Infinitesimal deformation no significant difference between the deformed and undeformed shapes Stress and strain are defined in the undeformed shape. 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 Nonlinear Finite Element Analysis Procedures.
