Analysis of in-plane transonically propagating interface crack with a finite contact zone

Abstract

The report of Lambros and Rosakis [(1995) J Mech Phys Solids 43(2): 169-188] has focused attention on steady-state transonic interfacial crack growth accounting for the phenomenon of crack face contact in elastic/rigid bimaterial but could not handle issues relating to energy transmission across the interface. The present paper attempts to provide a complete explicit expression of the asymptotic fields induced by transonically propagating interfacial crack in elastic/elastic bimaterial for in-plane case. The energy distribution on the contact area, crack tip and two singular characteristic lines is analysed thoroughly and compared with the dynamic separated J-integrals. The length of the contact zone is also discussed briefly by establishing energy fracture criterion that satisfies contact condition. The two-dimensional in-plane asymptotic deformation field surrounding the contact area of a crack propagating transonically along an elastic/elastic bimaterial interface is observed and discussed thoroughly.

Application of Interfacial Propagation and Kinking Crack Concept to ECC/Concrete Overlay Repair System

“…At certain instance, crack kinks out of the interface and will advance in one of the two materials. It is pointed out in [1,2] that questions, such as whether the crack lies on interface or advances along the interface or would kink out of the interface, are important in the design of the interface between overlay and substrate.…”
