Abstract
Formulas are presented which describe the effect of flat elliptical cracks on the effec tive thermal conductivity of an otherwise homogeneous body. The cracks are assumed randomly and isotropically distributed throughout the body, and may either be dry or composed of any material with a conductivity differing from that of the matrix. Effec tive conductivities depend solely upon a crack density parameter when the cracks are dry, and additionally upon a saturation parameter and the crack planform aspect ratio otherwise.Keywords
