Secondary crack trajectory for longitudinal shear problems

International Journal of Fracture Mechanics Aims and scope Submit manuscript

Abstract

In some practical problems the direction of crack growth is not colinear with the orientation of the pre-existing and unloaded crack. The longitudinal shear loading is one for which an analytical solution can be exploited and the strain energy variation with respect to relative orientation can be evaluated.

Résumé

On traite de l`orientation que peut prendre une fissure au départ d'une crique existante, en fonction de diverses conditions de mise en charge. Pour un type particulier de sollicitation, on développe le processus d'analyse qui permet de définir les conditions de propagation de la fissure; ce processus pourrait étre également appliquable à d'autres types de sollicitation.

Zusammenfassung

Dieser Bericht handelt über die Richtungen nach denen sich ein schon vorhandener Riss unter verschiedenen Spannungsbeanspruchungen weiter ausbreiten kann.

Es wird ein Untersuchungsverfahren entwickelt, welcher die Fortpflanzungsbedingungen für eine gegebene Beanspruchung zu ermitteln.

Dieser Verfahren ist auch für andere Arten von beanspruchung anwendbar.
