摘要
本文给出了弹塑性结构优化设计的序列二次规划算法,分别考虑了弹塑性结构分析,灵敏度分析和二次规划的Lemke算法的并行计算。针对弹塑性结构灵敏度的不连续性,比较了连续模型和间断模型的计算结果,结果是接近的。算例表明此算法有很好的并行性。
This paper discussed the parallel computing of the analysis of elasto plastic structures, sensitivity analysis, and the Lemke algorithm of quadratic programming. So the parallel algorithm for sequential quadratic programming of elasto plastic structures is obtained. This method has good parallel speedup and efficiency.
