The External Axisymmetric Interface Crack with Heat Flow

Two half-spaces of dissimilar material properties are brought together and bonded over a circular region of radius r = a to form an exterior axisymmetric interface crack. Loads are applied at infinity such that the common boundary (i.e. the bond and any contact region that develops) transmits tractions whose resultant is an axial tension P. Interpenetration is predicted if the track is assumed ...

Calculating Stress Intensity Factor for Small Edge Radial Cracks on an Orthotropic Thick-walled Cylinder Subjected to Internal Pressure using the Average Stress

In this paper, the problem of calculating the stress intensity factor (SIF) for an orthotropic thick-walled cylinder with a small radial crack subject to internal pressure is considered. The crack is assumed to be an edge crack on the external radius of the cylinder. The stress intensity factor is calculated by superposition of an uncracked cylinder with uniform stress distribution and a cylind...

The Interface Crack Problem Foranisotropic

The two-dimensional interface crack problem is investigated for ani-sotropic bodies in the Comninou formulation. It is established that, as in the isotropic case, properly incorporating contact zones at the crack tips avoids contradictions connected with the oscillating asymptotic behaviour of physical and mechanical characteristics leading to the overlapping of material. Applying the special i...

Stress Redistribution Analysis of Piezomagnetic Rotating Thick-Walled Cylinder with Temperature-and Moisture-Dependent Material Properties

In this article, the problem of time-dependent stress redistribution of a piezomagnetic rotating thick-walled cylinder under an axisymmetric hygro-thermo-magneto-electro-mechanical loading is analyzed analytically for the condition of plane strain. Using the constitutive equations, a differential equation is found in which there are creep strains. Primarily, eliminating creep strains, an analyt...
