摘要
结构极限分析是塑性力学的一个分支,在结构及机械设计中有广泛的应用。由于工程应用中受各种因素的影响,使得结构存在各种各样的缺陷。对该类结构进行极限分析研究,能反映结构的实际安全程度,而且能充分利用材料塑性性能的潜力。本文利用权余法中的配点法和子域法,结合塑性极限分析理论对含缺陷板和含缺陷圆柱壳结构进行了承载能力分析,得到了一些有意义的结果。
Structural limit analysis is a branch of plasticity, which is widely used in structural and mechanical design. Affected by outer factors in engineering, there are kinds of defects in structures. It can reflect the real safety of structures and completely explore the capability of material plasticity to study the limit analysis of these structures. Defective plate and cylindrical shell structures are studied in this paper using the method of weighted residuals, and some illustrative results obtained.
