结构毁伤强冲击光滑粒子流体动力学方法(SPH)重构核粒子方法(RKPM)强冲击载荷会严重威胁舰船生命力,对于冲击作用下舰船结构毁伤的精确预报是舰船防护设计和提高舰船生命力的重要环节.考虑到传统有网格算法在结构断裂模拟上遇到的挑战,本文在前期工作的基础上,建立了强冲击载荷作用下结构毁伤的完全无网格模型与计算方法,采用...
In the present work, numerical simulation of structural damage subjected to the near-field underwater explosion is carried out by coupling the SPH and RKPM. The fluid solver is established based on the compressible SPH method, while the dynamic response of the structure is calculated based on ...
