基于边界元法和显式有限元法，建立了气泡与弹塑性薄壁板相互作用的三维全耦合模型。该模型能准确计算作用在平板表面的气泡载荷，并能描述与平板两侧流场耦合的结构运动。由于薄壁板的弹塑性效应，气泡表现出吸引运动、排斥运动或分裂。
On the basis of the boundary element method and explicit finite element method, a three-dimensional fully coupled model is developed to investigate the interaction between a bubble and an elastic-plastic thin-walled plate. The model can accurately calculate the bubble loading acting on the plate surface and describe the structural motion coupling with the flow field on two sides of the plate. As a result of the elastic-plastic effects of the thin-walled plate, the bubble displays attractive motion, repulsive motion, or splitting.
