on the basis of the concept of the vertical crooked arm in material mechanics, a quantitave analysis of the distribution and evolution of horizontal shear stress in vertical folding is discussed.
根据材料力学纵弯桿概念,从定量角度分析了横向剪应力在纵弯褶曲中的分布和演化。
relation between the horizontal shear stress and lateral plastic deformation and relation between the vertical shear stress and axial plastic deformation are presented, respectively.
