Interaction Between an Incident Wave and a Dynamically Transforming Inhomogeneity
Transformation-toughening of ceramics has attracted considerable attention [1,2,3] in recent years. The key mechanism in this toughening is the stress-induced phase transformation of the partially stabilized zirconia (PSZ) inhomogeneities, which accompanies volumetric expansion. Due to this expansion, the composite material consisting of PSZ inhomogeneities in a brittle matrix becomes more resistant to fracturing. While this problem has been studied for guasi-static loadings [4,5], the corresponding dynamic case has remained relatively unexplored.
