The interface damage function (IDF) defining the fraction of damage on crystallite interfaces in a polycrystalline material1 is extended to include functional dependence upon individual crystallite lattice orientation of grains composing a boundary. The material studied was OFHC copper crept at 10 MPa and 0.6 Tm. Major peaks in the IDF were found through a series of projections of the eight-dimensional domain of the function. A maximum value of 0.95 was found for the IDF.
