This is the first "annual" report,,covering twelve months of the initial effort on this program. Progress is reported In the characterization of interfaces, the correlation of interfacial quality and global properties, the development of rests for interfacial effects, and the mechanics analysis of microstresses including interfacial effects. A salient result is the achievement of the first solution of interfacial stresses in materials which have locally nonuniform I roperti es.
