The response of partially transparent materials subjected to rapid near-surface energy deposition is characterized by various phenomena including thermal degradation, polymer pyrolysis, and dynamic stress effects resulting in spallation failure. This paper addresses the role of each of these phenomena in the assessment of material degradation due to near-surface energy deposition. Analytical expressions are developed to determine the effect that energy intensity and pulse duration have on each of these phenomena for broad material categories. Approximate solutions are used to determine the dominant phenomena.
