Interface cracks with surface elasticity in anisotropic bimaterials

Bridged interface cracks in anisotropic bimaterials

The bonding strength between dissimilar materials in composites is often relatively weak. Interface debonding and cracking are of common occurrence. As an e€ ective method to minimize such failures, ® bre stitching is used to enhance the bonding strength when joining layers in polymer composites. With the presence of the reinforcing ® bre, the overall elastic response for each component of the ...

On Stationary and Moving Interface Cracks with Frictionless Contact in Anisotropic Bimaterials

Multiple cracks in thermoelectroelastic bimaterials

The formulation for thermal stress and electric displacement in an in®nite thermopiezoelectric plate with an interface and multiple cracks is presented. Using Green's function approach and the principle of superposition, a system of singular integral equations for the unknown temperature discontinuity de®ned on each crack face is developed and solved numerically. The formulation can then be use...

Screw dislocation interacting with interface and interfacial cracks in piezoelectric bimaterials

Interface and interfacial cracks interacting with screw dislocations in piezoelectric bimaterials subjected to antiplane mechanical and in-plane electrical loadings are studied within the framework of linear piezoelectricity theory. Straight dislocations with the Burgers vector normal to the isotropic basal plane near the interface or interfacial crack are considered. The dislocations are chara...

Singular Perturbation Solutions of a Class of Systems of Singular Integral Equations

A new class of systems of strongly singular integrodifferential equations is examined, which emerges in the study of the bridged interface crack growth, e.g., in fiber stitched layered composites. This work generalizes the asymptotic analysis of strongly singular integral equations by Willis and Nemat-Nasser [Quart. Appl. Math., 48 (1990), pp. 741–753]. Singular perturbation solutions up to the...
