槽钢在约束扭转下的实验应力分析

Experimental stress analysis of tank-type steel in restrained torsion

研究了薄壁杆件约束扭转下截面的内力及扭角φ的表达式,利用电测法,测出构件截面的应变,利用应力应变间的关系,计算出截面的应力,并将实验值与理论值相比较,检测了理论与实验的相符程度。

Research on the expression formula of the interior power formula of the section under restrained torsion of thin-walled bean and its twist angle φ We can use electrometric method to measure distortion of section, using the cormection between stress and distortion, computs the stress of section, then we compare the experimental value with the theoretical value to check if they can go along with each other.
