摘要

In this paper, the interaction of multiple cracks in an infinite plate subjected to remote stress and heat flux is investigated. The problem is formulated as two sets of singular integral equations, corresponding to the heat flux problem and the stress problem, respectively. The equations for heat flux is first solved for the unknown temperature jump function, which later be used to solve for the crack opening displacement function in the heat stress equation. This method does not require a direct solution of the heat flux problem. Subsequently, the stress intensity factors for various double-crack configurations are computed and presented.
