A quasistatic crack propagation model allowing for cohesive forces and crack reversibility
Peter Philip

 
Abstract
    While the classical theory of Griffith is the foundation of modern understanding of brittle fracture, it has a number of significant shortcomings: Griffith theory does not predict crack initiation and path and it suffers from the presence of unphysical stress singularities. In 1998, Francfort and Marigo presented an energy functional minimization method, where the crack (or its absence) as well as its path are part of the problem
 
Key Words
    crack propagation; brittle fracture; cohesive forces; reversibility; energy minimization.
