The Analysis of Laser Thermosplitting of Fragile Materials by Using of Special Geometry Beams

Abstract: In this paper the numerical modeling of allocation of thermoelastic fields which are formed during controllable laser thermosplitting in fragile nonmetallic materials is executed within the limits of theory of elasticity. Modeling is executed for laser beams with a cross-section in the form of an ellipse, a circle, and the semi-ring and theirs combination. The classical circuit of realization of the given method consists of the superficial heating of a material by a laser beam and the aftercooling of this zone… Show more

“…The deviation mechanism of the trajectory is explained by analyzing the results of the stress field. In 2011, Shalupaev S et al [24] carried out modeling and simulation analysis on laser beams with ellipse, normal circle, semiring shape and their combined shape. They also utilized coolant to cool the heated area, and analyzed the influence of heat source shape on cutting trajectory and the change of stress area after cooling.…”
