Abstract
When a heterogeneous elastic material is represented by an effective h omogeneous elastic solid, average stress and strain fields are used. T he meaning of the J-integral in the effective homogeneous solid is inv estigated. A periodically layered medium is considered. The relation b etween the J-integrals in the original layered medium and the effectiv e medium is derived.
