Abstract
This paper concerns fracture dynamic problems for elastic cracked solids with allowance for crack faces contact interaction. The contact problem for a penny-shaped crack with an initial opening under normally incident tension-compression wave is solved by the method of boundary integral equations. The contact forces and the displacement discontinuity of the crack faces are studied. The solution is compared with those obtained without allowance for crack faces contact interaction for various shapes of the initial opening. (c) 2007 Elsevier Ltd. All rights reserved.
