| Abstract | A method of the thermovision study for solving the problems of the experimental mechanics is presented. The method of the experimental study of deformation and fracture is based on the registration and interpretation of the infrared radiation pattern of a sample, which is caused by plastic deformations and material fracture. The thermofilm shows the kinetics of the sample deformation. Thermograms allow estimation of the plastic deformation zones. The characteristic changes in the temperature of a sample correspond to the limiting states of the material. Examples of studying the deformation and fracture of constructional steels under the conditions of the homogeneous and heterogeneous limiting states with the use of the thermovision method are given. |
