圆柱壳在中央面承受冲击荷载时的塑性动力响应的近似解法

AN APPROXIMATE SOLUTION OF THE PLASTIC DYNAMIC RESPONSE OF CYLINDRICAL SHELLS UNDER IMPACT LOADING ON A MEDIAL CROSS SECTION

在文献[1]的基础上进一步将加权余量法用于壳体的塑性动力响应问题。采用加权余量法中的配点法和子域法,求出简支圆柱薄壳在中央面承受冲击荷载时的塑性动力响应和阻尼介质对其的影响。

On the basis of a previous paper by the same author, the weighted residual method is further applied to the plastic dynamic response of shells. By using the approaches of collocation and subdomain in the weighted residual method, approximate solution of the plastic dynamic response of cylindrical shells on a medial cross section, when simply supported and under impact loading, are worked out. Also found out are effects of the damping medium on the response.
