FINITE-ELEMENT ANALYSIS BASED UPON THE GENERALIZED VARIATIONAL PRINCIPLE OF PLASTIC AND ELASTIC DISTORTION OF PLATES AND SHELLS

Generally speaking, it is difficult to analyze distortion and thermal stresses in a structure due to non-uniform temperature distribution during welding. Especially, the elastic-plastic analysis of such structures is extremely difficult, if not impossible, to solve by the analytical procedure. The finite-element method was originally used for the vibration analysis and the stress analysis of airplane structures. As the method is recognized as a powerful tool in the approximate numerical calculation, it begins to be widely applied to various fields, as well as to a structural one. The finite element model in this paper is derived from the variational principle which contains the complementary energy implicitly because strain components are treated as independent variables in each element and eliminated from an element matrix with the help of variation.
