An Interpretation of the J-Integral in the Inelastic Fracture of Ceramics

Creators

Description

Automatic translation: The energy density criterion of the process zone was physically interpreted in 1972/76. According to this, the dissipative energy density consumed by microfracture should correspond to the increase in the elastic deformation energy density. In this report, this fracture criterion is formulated and interpreted using the J-integral. Initial comparative evaluations with references to literature and suggestions for solutions to current problems are provided.

Abstract (German)

Das Energiedichtekriterium der Prozeßzone wurde 1972/76 physikalisch interpretiert. Danach soll die durch Mikrobruch verbrauchte dissipative Energiedichte der Zunahme der elastischen Verformungsenergiedichte entsprechen. In diesem Bericht wird dieses Bruchkriterium mit Hilfe des J-Integrals formuliert und interpretiert. Erste vergleichende Bewertungen mit Literaturangaben und Hinweisen für die Lösungen aktuell anliegender Probleme verden mitgeteilt.
