A thermal problem of friction for a half-space with a crack
Journal of Engineering Physics and Thermophysics, 1999We investigate the effect of local frictional heating of the surface of a half-space on the stress intensity factors at the vertices of a surface cut.

FUNDAMENTAL SOLUTION OF THE CRACKED DISSIMILAR ELASTIC SPACE
Computational Methods in Sciences and Engineering 2003, 2003Fundamental solutions are used in the Boundary-Integral Equation analysis to determine the stress or/and displacement fields of finite elastic bodies subjected to external loading. Especially for crack problems, the method of Fundamental Solutions give more accurate results because they completely satisfy part of the boundary conditions of the problem.

Interface crack in the inhomogeneous transversely isotropic space
Materials Science, 2012We construct the exact solution of the problem of circular interface crack in an inhomogeneous transversely isotropic space under the action of arbitrary loads applied to the crack lips. The formulas for the stress intensity factors on the boundary of the crack and the values of these factors for some combinations of transversely isotropic materials ...

Elastodynamic analysis of nonplanar cracks in a half-space
Acta Mechanica, 1996A boundary value problem for the wave equation is discussed for the half-plane without straight segments. The problem is reduced to a system of singular integral equations with the dominant part of Hadamard's type. This system is solved by Galerkin's numerical scheme.

An eigenvalue problem for elastic cracks in free space
Mathematical Methods in the Applied Sciences, 2009Summary: We study in this paper an eigenvalue problem for the linear elasticity equations in three-dimensional space. The problem is defined in the whole space cut by a planar crack. The eigenvalue appears in a linear condition relating the traction to the jump in displacements across the crack.

Crack Spacing in Brittle Films on Elastic Substrates
Journal of the American Ceramic Society, 1990An approximate, analytical solution is derived for the minimum spacing that can exist between a series of parallel cracks propagating in a thin film. The analysis is pertinent to the specific case of a film and substrate having identical elastic properties. In the absence of plasticity, only three parameters govern the minimum crack spacing. The cracks

Interaction of a Punch with a Conical Crack in Half Space
1988In this study, an axially symmetric elastic half-space which contains a conical crack indented by a punch with various geometries is considered. By using Papkovich-Neuber functions and Hankel transform techniques the problem is reduced to a system of three singular integral equations by assuming that the contact along the interface is frictionless and ...

Crack Control through Bar Spacing Requirements
Structures Congress 2005, 2005In the ACI 318-99 building code, new design provisions were introduced for the control of cracking through reinforcing bar spacing requirements. With the introduction of the ACI 318-05 code, the direction of controlling cracking through reinforcement spacing with be further extended. The new provisions provide for the control of flexural cracking along
