【摘要】 当剪力或轴力较大时,用纯弯曲方法计算弯矩误差很大。该文对弯矩、剪力及轴力联合作用下的板料弯曲提出了一个力学模型,并按此导出了有关的计算公式。更多还原

【Abstract】 When shearing force or axis force is relatively great, great errors of moment arise when the method of pure bending is employed. A mechanics model is presented in this paper which explains the combinative action of bending moment, shearing force and axis force, and some related calculation formulas are hereby deduced.更多还原
