The paper is a part of the larger study on the effects of high-energy beam of laser radiation on high strength concrete. Surfaces of concretes have been exposed to a single impulse of energy from impulse neodymium laser and analysed with application of computer aided optical microscopy. Theoretical model presented here is based on the normal distribution of thermal source. The brittle fracture of material caused by the thermoelastic state of stress is described by the fracture theory given by Griffith as well as McClintock and Walsh. Numerical analysis of temperature fields, corresponding stresses and thermal fracture criteria are also presented here.
