摘要
通过对板料弹塑性弯曲变形分折 ,利用材料力学中的平面曲杆理论 ,提出了大曲率弹性变形应变中性层向内移动的观点 。
In this paper,author analyzes elastic plastic deformation of plate on the basis of the theory of plane curving pole in the material mechanics,and puts forward a viewpoint in which its strain neutral layer displaces toward inside when the plate comes into being big curvature elastic deformation, also deduces a formula on calculating plate bending thinning coefficient
