Methods of Pulsed Laser Annealing of Nonmetallic Plates

Resumo

Three methods of pulse laser annealing of nonmetallic plates are examined on the basis of the quasistatic problem of thermo-elasticity. It is shown that the maximum tensile stresses in the machined plates can be reduced several-fold and the energy expenditures associated with machining can be reduced by about 20 – 40%. The thermal strength criteria for plates are obtained for the laser annealing methods indicated. The results obtained are checked experimentally.
