SIMULATION OF NON-PLANAR CRACK PROPAGATION IN THREE-DIMENTIONAL STRUCTURES IN CONCRETE AND ROCK. FRACTURE OF CONCRETE AND ROCK: RECENT DEVELOPMENTS. PAPERS PRESENTED AT THE INTERNATIONAL CONFERENCE, UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, SEPTEMBER 20-22, 1989

The purpose of this paper is to describe features for simulation of crack propagation being implemented in the Fracture Analysis System (FRANSYS,) a fracture simulation system currently under development at the Program of Computer Graphics at Cornell University. Routines for the computation of stress intensity factors for three-dimensional cracks in arbitrary bodies are described. An example application is presented and compared with an analytical solution. Features to update the model to accommodate additional surfaces required by crack propagation are also described. Preliminary results for three-dimensional crack propagation are presented in an example application.(A) For the covering abstract of the conference see IRRD 829348.
