| 摘 要： | 本文讨论了置于液体表面上的梁在一般的非对称变形模式下的塑性动力响应问题。文中采用了复域内格林函数解法,将势函数的Herbert问题转化为对Cauchy型奇异积分方程的求解。并用此方法讨论了简支梁和悬臂梁的塑性动力响应问题。结果表明,这类问题的已有的解均为本文给出的一般变形模式下解的特例。

| Abstract: | This paper discusses the dynamic response of beams resting on fluid withthe general asymmetric deformations assuming that the fluid resistance is related to the velocity potential of the fluid. The Green's function in complex domain is introduced to turn the mixed boundary value problems of the fluid potential to the problems of Cauchy's dual integral equation. In this way, the response of simply supported beams and cantilever beams is discussed. Obtained results demonstrate that the solution given by D. Krajcinovic 1] is only a particular case of the more general solution shown in this paper. |
