Quasi-static evolution of delaminated structures: analysis of stability and bifurcation (Q1434736)

This paper deals with the evolution of delaminated structures represented by a frame of plates. The goal is the introduction of a global formulation for the rate problem, when the propagation is governed by a Griffith criterion. This new formulation enables to analyze the existence and uniqueness of the solution of this problem. Moreover, the authors study the stability and bifurcation in the propagation of delamination in the modeled delaminated plates. Finally, analytical applications of this formulations to simple structures are presented.
