Abstract
A two-dimensional model of a film bonded to an elastic substrate is propose d for simulating crack propagation paths in thin elastic films. Specific ex amples are presented for films subject to equi-biaxial residual tensile str ess. Single and multiple crack geometries are considered with a view to elu cidating some of the crack patterns which are observed to develop. Tendenci es for propagating cracks to remain straight or curve are explored as a con sequence of crack interaction. The existence of spiral paths is demonstrate d. (C) 2000 Elsevier Science Ltd.
