摘要：

A circular, magnesium fluoride ring was irradiated with a Q-switched, neodymium-doped glass laser. The sudden absorption of laser energy by the ring produced an internal temperature distribution which could be closely approximated by a cosine function over half the circumference of the ring. The ensuing membrane strains were measured with semiconductor strain gages. Measured strain-time histories were found to be in close agreement with theoretical predictions. © 1972 by ASME.
