Análise dinâmica linear por superposição modal de cascas finas arbitrárias pelo Método dos Elementos Finitos

The main purpose of this work is to study the linear dynamic behavior of arbitrary thin shells by the Finite Element Method. Plane triangular elements with eighteen degrees of freedom each are used. The general equations of movement are obtained from the Hamilton Principle and solved by the Modal Superposition Method. The presence of a viscous type damping can be considered by means of percentages of the critical damping. An automatic computer program was developed to provide the vibratory properties and the dynamic response to several types of deterministic loadings, including temperature effects. The program was written in FORTRAN IV for the BURROUGHS B-6700 computer. Finally, some numerical examples are presented.
