The nonlocal friction law proposed by Oden et al. was adopted in order to consider the nonlocal friction effect of the asperities on the rough contact surface between the die and the workpiece in several kinds of metal plastic forming problems.The mechanical equilibrium equations with the integral-differential form were obtained by using the engineering method or slab method, and solved approximately by using the perturbation method. The normal stress distributions on the contact surfaces in metal forming problems with nonlocal friction were obtained, and the factors which affect the nonlocal friction effect were analyzed.

反向条纹投影技术是一种应用于在线或批量检测的快速而稳定的光学三维面形检测技术。提出了一种新的产生反向条纹的算法,新的算法建立投影器坐标系与摄像机坐标系的正向映射变换关系,通过投影器坐标系上一个像素点的两套相位值,找到其在摄像机坐标系中对应的位置,即产生投影器坐标系像素点在摄像机坐标系中的注册。由于期望在摄像机中观察到的条纹图像只是简单的正弦条纹图像,直接读取注册点的期望条纹相位,很容易产生反向条纹
