Abstract

Microcracks influence on the elastic properties of a material has been studied extensively through various modelling approaches. This paper aims to further the inquiry into thermal properties, considering both steady-state conduction and thermoelasticity. Taking into account the induced anisotropy (due to the oriented nature of cracks) and unilateral effect (different behaviour whether cracks are open or closed) remains an open research field. Using homogenization techniques, this work intends to present closed-form estimates of the effective thermal properties of a media weakened by arbitrarily oriented microcracks with unilateral behaviour.
