Abstract

A investigation was made of volumetric failure in silicate glasses K-8 and F-5 and in polymethylmethacrylate (PMMA), and the energy-time characteristics were recorded for the start of the stage of the formation of damage in these materials due to a laser beam. The article discusses a model of the failure of silicate glasses as a result of the absorption of light at microdefects, as well as a model of the formation of cracks from high-temperature sites in polymers, taking account of the durability of the material. An evaluation is made of the power density q and the energy ɛ in the proposed mechanisms for the failure of transparent dielectrics.
