Photoelectric-Computer Data Processing(PCP) Program in Experimental Photo-Stress Analysis

摘要: 本文提出的光弹性数据自动分析处理PCP程序,使输入计算机的数据数量达到最小限度.文中采用陈至达^[1](1962年)的光测应力分析基本方程,并导出适合于光弹性数据处理的三次样条函数.初步实践证明PCP程序较目前其他研究者提出的自动应力分析方法更为准确和节省计算时间.

Abstract: In this paper, a photoelectric-computer data processing(PCP) program in experimental photo-stress analysis is presented. Basic equation of photoelastic stress analysis by Chen(1962) is adopted;and a cubic spline function suitable for processing of photoelastic data is derived. This program requires least data input to computer comparing with and other programs It has been proved that the PCP program is more accurate and requires least vomputing time than other methods so lar as we know.
