BEHAVIOR OF THERMAL STRESSES IN A RAPIDLY HEATED THIN PLATE

摘要

Using the hyperbolic heat conduction model, thermla stresses generated within a rapidly heated thin metal plate are investigated numerically. The effects of different paraemters scuh as the form, duration, amplitude, and penetration depth of the heating soruce on the temperature, thermla moment, deflection, and thermla stresses are studied. Itis found thwat under ultra-fast heating of very thin plates, the hyerbolic heat conduction model must be adopted to modle the thermal behavior.
