| 摘 要： | 旨在开发一个简化公式,用于双向剪压作用下简支板的临界屈曲应力计算。运用经典板理论和里兹法对不同面积比的板临界应力进行计算。根据二维平面内应力关系,由经验判断推出四维临界应力公式,该公式表现为3个平面内应力和面积比的关系。计算结果表明:1)面积比在1~2时,临界应力与面积比成线性关系,2~5时为非线性关系;2)当剪切应力接近其临界值时,临界应力关系呈现更明显的线性变化趋势,同时面积比对其影响减弱。

| Abstract: | This study aims to develop a concise formula for the critical buckling stresses of a simply supported plate under biaxial compression and shear. The critical stresses are obtained for different aspect ratios using classical plate theory and the Ritz method. The four-dimensional critical stress formula, which is expressed in terms of the three in-plane stresses and the aspect ratio, is developed empirically according to the two-dimensional relationships between the in-plane stresses. The findings that are of... |
