悬臂梁在倾斜载荷作用下的弹塑性大挠度分析 总被引:3,自引:0,他引:3
作为Plastica理论[12]的应用,本文分析了理想弹塑性矩形截面梁在自由端承受倾斜集中力作用时塑性区扩展阶段的大挠度变形.着重讨论了集中力的倾角对弯曲形状、载荷—挠度关系及塑性区长度的影响.结果用解析解和数值解同时给出. 相似文献

An analysis of the large deflection of an elastic-plastic cantilever subjected to an inclined concentrated force 总被引:1,自引:0,他引:1
Based on the Plastica theory(see ref.[12]),the large deflection of an elastic-perfectlyplastic cantilever subjected to an inclined concentrated force at its tip,before the unloadingin the plastic region occurs,is analyzed in this paper.The emphasis of the analysis is put onthe effects of the angle of inclination of the concentrated force upon the deformed shape,theload-deflection relationship and the length of the plastic region.Both analytical andcomputed results are given. 相似文献
