Effect of Thermomechanical Loading on an Edge Crack of Finite Length in an Infinite Orthotropic Strip

The purpose of this article is to determine the effect of thermal loadings on the stress intensity factor of an edge crack of finite length in an orthotropic infinite strip of finite thickness under mechanical loading. Analytical expressions of the stress intensity factor at the crack tip in point and arbitrary constant loadings are found. Numerical values of the factor at any arbitrary location on the crack face due to mechanical loading and effects of thermal loadings are computed for various crack lengths in an orthotropic material composite, and the results are presented in the form of graphs. The effects of thermal conductivity parameters on the stress intensity factor for different particular cases are also shown graphically.
