| 520 | |a Abstract An open question of interest to the mechanics of interface fracture is how to generalize the Comninou contact model for interface cracks in isotropic solids to the general anisotropic case. Part of the difficulty lies in that the peculiar oscillatory behavior can not be fully eliminated by Comninou's original assumption of pure pressure contact between the crack surfaces. In this paper, we propose a model that strictly enforces the non-oscillatory condition by allowing the crack face contact force to have a shear component normal to the direction of slip, which is somewhat reminiscent of frictionless slip between a pair of grooved surfaces. Based on that model, complex variable representations are adopted to determine the complete series expansion for the crack-tip field. The solutions are incorporated into a hybrid finite element procedure to develop a special element for closed interfacial crack tips obeying the generalized contact model. Numerical examples involving a partially closed crack between a pair of misoriented cubic crystals are given to illustrate how the special crack-tip element helps in determining the stress intensity factors as well as the contact zone geometry. | ||

A generalized comninou contact model for interface cracks in anisotropic elastic solids |
| abstract |
Abstract An open question of interest to the mechanics of interface fracture is how to generalize the Comninou contact model for interface cracks in isotropic solids to the general anisotropic case. Part of the difficulty lies in that the peculiar oscillatory behavior can not be fully eliminated by Comninou's original assumption of pure pressure contact between the crack surfaces. In this paper, we propose a model that strictly enforces the non-oscillatory condition by allowing the crack face contact force to have a shear component normal to the direction of slip, which is somewhat reminiscent of frictionless slip between a pair of grooved surfaces. Based on that model, complex variable representations are adopted to determine the complete series expansion for the crack-tip field. The solutions are incorporated into a hybrid finite element procedure to develop a special element for closed interfacial crack tips obeying the generalized contact model. Numerical examples involving a partially closed crack between a pair of misoriented cubic crystals are given to illustrate how the special crack-tip element helps in determining the stress intensity factors as well as the contact zone geometry. © Kluwer Academic Publishers 1994 |
