TL;DR: The equations of caustics for quasistatically or dynamically extending curvilinear interface cracks are derived where optical isotropy and anisotropy of the material, respectively, have been considered as mentioned in this paper.

TL;DR: In this article, the quasistatic thermal crack propagation in self-stressed unidirectionally reinforced composite structures with a low-fiber volume fraction has been investigated and the resulting mixed boundary value problems of the stationary plane thermoelasticity are solved numerically by using standard finite element programs.

TL;DR: In this article, the relationship between the total energy release rate G and the complex stress intensity factors K j (j= 1,2), respectively, was studied existing at the crack tip of a semi-infinite curvilinear interface crack.

TL;DR: In this paper, the influence of a circular transforming inclusion on the stress field of an antiplane shear crack is investigated and the analytical expressions for the stress intensity factor KIII and its values vary with the size, position and stress free strains of the transforming inclusion.

TL;DR: In this paper, the stress distribution of brittle fiber-ductile matrix composites under thermal and tensile loads is analyzed and an approximate analytical method is proposed by using the micromechanical approach of composite mechanics.
