摘要： Tile reverse-bulge motion (RBW) in the metallic foils. which is induced by spatially cylindrical long pulse laser. is examined in order to analyse the newly-discovered reverse-plugging effect (RPE). An uncoupled, thin plate theory is Used to determine the induced. flexural vibrations. The solution is obtained as the superposition of two displacement. fields, representing the quasi-static and the dynamic behaviors.Meanwhile. the equivalent thermal loading and the dimensionless analysis of thin plate motion are presented. Numerical results presented may partially explain the RBM of thin plate at the early stage of laser irradiation.
