Influence of elastic and thermal mismatch on the local crack-driving force in brittle composites

An expression is derived for the change of localK1 value of a crackfront near circular and spherical inclusions with elastic moduli and thermal expansion coefficient different from those of the matrix. The derivation is based on the concept of an “image stress” which is imposed on the crack, to illustrate the interaction between elastic and thermal stress concentrations developed around inclusions in a composite material and the crack-tip stress field.
