elastic bucking meaning in Chinese

弹性挤曲
弹性屈服
弹性压屈

According to the elastic bucking theory this paper reviews and compares the calculations that such member bend around the reat axis and the hollow axis as well as bend with torsion around the hollow axis . here this paper presents a formula of calculating b used in with the h - shaped anglicizing element . meanwhile , this paper deduces out a formula of calculating b . by , which the member could be controlled to only buckle around the real axis
本文根据弹性屈曲理论对双肢格构式单轴对称缀板柱绕实轴、虚轴以及弯扭屈曲进行了计算分析和比较，提出了绕虚轴侧向屈曲的换算长细比_ ( oy ) = ( y ~ 2 + l ~ 2 ) ~ ( 1 / 2 )中的值用h计算单元指出的计算公式，同时推导出了单轴对称缀板柱只出现绕实轴弯曲屈曲的最小肢间间距b 。
