摘　　要：在分析三维光塑性基本理论的基础上,以MATLAB软件为平台,依据牛顿迭代法的原理,采用M语言编程求解了楔横轧制件内部的三维应变分布,成功地实现了对楔横轧工步的光塑性数据处理和分析,提高了数据处理效率和计算精度,所得应变分布与实验结果吻合.In this article,based on the radical three-dimension photoplasticity theory,the three-dimensional strain distribution in the part of cross wedge rolling was solved by using the Matlab as a programming tool and Newton iterative method as a solution theory.With the M-language,the author compiled some logical (procedures) so that the analysis of photoplasticity and the data processing of cross wedge rolling photoplasticity was accomplished successfully.It enhanced the efficiency and precision of the data processing,and the analysis (results) of the strain distributing accorded with the fact.
