用分域型矩量法分析阻尼介质对壳体塑性动力响应的影响

Applying Subregion Moment Method to Analyze the Effect Of Damping Medium on Plastic Dynamic Response of Shell

本文给出分域型短量法，并将其应用于壳体塑性动力响应问题。文中以承受均布冲击侧压的固支长圆柱壳为例，应用分域型矩量法分析阻尼介质对其塑性动力响应的影响。

In this paper, the subregion moment method is given out and applied to the plastic dynamicresponse of shell. Take the long cylindrical shell on fixed supports when the shell suffered a side pressureof uniform impact loading as example, the effect of damping medium on the plastic dynamic response isgiven out by the subregion moment method in this paper.
