Fracture dynamics of rock

  • Z. T. Bieniawski
Article

Abstract

A concept of fracture dynamics of rock is introduced, three aspects of fracture being discussed, namely: stability of fracture propagation, terminal fracture velocity and dynamic stresses created by a propagating crack.

Work related to this new field of research is reviewed and theoretical and experimental studies on rock are reported. The practical significance of the fracture dynamics concept in rock mechanics is outlined.

Résumé

L'idée de la dynamique de rupture dans la roche est introduite; trois aspects des ruptures sont examinés, à savoir: la stabilité de la propagation de la rupture, la vitesse finale de la rupture, et les contraintes dynamiques créées pal une rupture qui est propagé.

Un compte-rendu est fait sur les travaux executés dans ce domaine nouveau de recherche, et les études théoriques et les expériences pratiques sont passées en revue. L'importance pratique de l'idée de la dynamique de la rupture dans le domaine de la mécanique des roches est donnée.

Zusammenfassung

Der Begriff der Bruchdynamik von Gesteinen wild eingeführt, wobei drei Erscheinungen des Bruchvorganges diskutiert werden, und zwar: Stabilitat der Bruchfortpflanzung, Grenzgeschwindigkeit der Bruchfort pflan zung and dynamische Spannungen, die durch einen sich fortpflanzenden Bruch erzeugt werden.

Die für dieses neue Forschungsgebied einschlägige Literatur wild besprochen und theoretische und experimentelle Untersuchungen an Gestein werden dargelegt. Die praktische Bedeutung des Begriffes der Bruchdynamik für die Gebirgsmechanik wild erlautert.
