分析结构跳跃问题的自适应参数增量迭代方法

The Adaptive Parameter Incremental Method for The Analysis of Snapping Prohlem

通过对Ｒｉｋｓ切线弧长法和Ｃｒｉｓｆｉｅｌｄ圆弧长法的综合及改进，本文提出分析结构跳跃问题的自适应参数增量迭代方法，并建立相应理论基础。最后文中给出中心分布压力作用下圆底扁球壳跳跃问题的数值结果。

By improvement of Rik's and Crisfield's arc length type method,the adaptive paratmeter incremental method is presented for predicting the snapping response of structures. Its justification is fulfilled, Finally, the effectiveness of this method is demonstrated by solving the snapping response of spherical caps subjec-ted to centrally distributed pressures。
