【摘要】 研究了一周边固定的扁薄锥壳在温度载荷和横向载荷共同作用下的过屈曲问题.利用数值计算的方法,得到了温度载荷?横向均布静载荷和扁壳横向大挠度位移的关系曲线,可以明显看出扁壳结构的平衡路径随载荷的变化存在跳跃现象,并给出了一个特殊情况可能存在的几种不同的过屈曲构形.更多还原

【Abstract】 The post-buckling behavior of a clamped flat shallow conic shell subjected to the transverse load at varying temperature is studied. Using numerical method, the relationship curves of the temperature load, transverse uniform static load, and shell’s transverse large displacement are obtained. It can obviously be seen that the jumping of the equilibrium path is inexistence when the load vary. Several different post-buckling configurations which may probably happen in a special case are given, also.更多还原
