摘要
对有初始曲率平板的弹塑性纯弯曲进行了详细的理论分析,导出了其应力与应变的计算公式,从理论上证明了曲板在完全塑性弯曲阶段中性层面位置将向内移动,并给出了中性层面半径的计算公式。
The paper has analyzed the strain and stress of curved wide border when they were bent, and has deduced some formulas to calculate the stress and the strain by elastic - plastic curving. The author has pointed out the moving of the neuter surface. The author has also provided the formulas to calculate the radius of neuter curved surface.
