摘要:
对结构分析中可能存在的病态矩阵,如不采取必要的措施会造成计算结果的严重失真.本文研究解的准确性,指出在结构分析中病态矩阵可能存在条件和其本质以及电算过程中应采取的措施.
Abstract:
This paper studies the accuracy of solution for a structure.Owing to the probable existence of ill-conditioned matrix,some countermeasures have to be taken so as to avoid the lack of fidelity. With respect to the ill-conditioned matrix in structural analy
