Title in Portuguese
Utilização da formulação livre para desenvolvimento de um elemento de membrana com liberdades rotacionais
Keywords in Portuguese
Elemento finito - membrana
Formulação livre
Graus de liberdade rotacionais
Abstract in Portuguese
Neste trabalho aborda-se o desenvolvimento de um elemento finito de membrana com graus de liberdade rotacionais e sua implementação a um sistema computacional em elementos finitos. O trabalho é baseado na formulação livre de BERGAN & NYGARD (1984) que produz um elemento simples e de bom desempenho. Aspectos fundamentais da formulação livre, do desenvolvimento do elemento e sua implementação ao sistema são apresentados. Resultados obtidos em alguns exemplos comprovam a eficiência do procedimento.

Finite Element - membrane
Free formulation
Rotational degrees of freedom
Abstract in English
In this work the formulation of a membrane finite element with rotational degrees of freedom and its implementation to a finite element computational system is presented. The development is based on the free formulation of BERGAN & NYGARD (1984) that produce a simple and efficient element. Fundamental aspects of the free formulation, of the element evaluation and its implementation to the system are shown. The results obtained in some examples indicate the accuracy of the procedure.
