Abstract

Neste trabalho calculam-se os fatores de intensidade de tensão de uma trinca interna elíptica-hiperbólica homofocal. Tal problema foi investigado à luz dos conceitos da teoria da elasticidade e da mecânica da fratura através da análise complexa onde a transformação conforme (a trinca foi transformada em um ciclo unitário) e a integral de valor principal de Cauchy são envolvidas. Os resultados foram comparados com outros já obtidos numericamente. As fórmulas encontradas por este trabalho podem ser utilizadas como referências para determinar rapidamente os fatores de intensidade de tensão das trincas emitidas de uma elipse ou um ciclo.
