【摘要】 给出了工程构件危险点在平面应力状态σx、τx、σy=σz=0时,第三、第四强度理论的判据.而判据中测取的数据,只需在危险点处粘贴两枚电阻应变片便可以获得,使得电测应变实验和强度计算更为方便简捷.更多还原

【Abstract】 The judgment of strength theory of the dangerous point of the engineering components was given in this paper when the plan stress state σ\-x、τ\-x、σ\-y=σ\-z=0.The measured date can be obtained only by sticking two resistance strain sheets at the dangerous point, which made electrical measurement test and the strength calculation more convenient and simple.更多还原
