Determinação de Factores de Intensificação de Tensões Mediante o Cálculo da Integral J Usando um Processo Adaptivo

Abstract

In this paper, an adaptive process using remeshing (1) is applied to FEM analysis and the influence of discrete domain optimization in the evaluation of stress intensity factors by means of the J integral calculation is analised for a cracked rotating disk and a cracked membrane. The error estimator proposed in (2) is used as a basis for the remeshing and the results are discussed.
