Within the framework of the theory of thermoelasticity, a comparative analysis of the fields of thermoelastic stresses arising in multilayer glass structures (triplex) in the process of two-beam controlled laser thermal cleavage is carried out. In this case, a series of channels perpendicular to the surface of the material is preliminarily applied along the processing line. It is shown that in the presence of channels, the magnitude of the maximum tensile stresses increases significantly and depends on the radius of the channels, the distance between them and the processing parameters. A series of applied channels along the machining line allows control of crack initiation and propagation along the machining line along curved paths.
Keywords: thermal cleavage, modeling, finite element method, temperature, triplex, thermoelastic stresses.
