| 摘 要： | 近期发展的修正的虚拟介质方法(MGFM)已经成功应用于求解多介质流动问题.本文研究了近体水下爆炸中强激波对薄板冲击的演变及薄板的动力响应过程.为了真实地考虑不同介质在界面处的非线性相互作用,本文将MGFM推广应用于处理流体与弹性薄板的相互作用.研究发现尽管流体和薄板结构的模拟基于各自不同的求解方法,但是用修正的虚拟介质...

| Abstract: | The modified ghost fluid method(MGFM) has been successfully applied to solve the multi-medium flow problem.In this paper,evolution of strong shock impacting on thin plate and dynamic response of the thin plate were investigated.We extended the MGFM to treat the flow and thin plate nonlinear interaction at the interface.Results disclose that the MGFM provides a convenient and effective way for handling the coupling of flow and thin plate,although the simulations of flow and plate structure are respectively b... |
