三维光弹性内部应力分析方法有多种,目前广泛采用的经典方法为切力差法.1980年Boris M.Barishpolsky提出实验与数值解联合求解的方法,国内也曾有人提出建立新的补充方程,以及用全息光弹性方法来建立补充方程.本文在前人研究的基础上,提出了一组方程做为补充方程,其目的是充分发挥光弹性实验和数值计算方法中各自的长处,将两者结合起来,进行三维应力问题求解.
The three-dimensional photoelastic internal stress analysis method has many kinds, the classical method widely used nowadays is the difference of the shear force method. In 1980, Boris M. Barishpolsky proposed the method of joint experiment and numerical solution, some people also proposed some new supplementary equations in China, And using holographic photoelastic method to establish supplementary equations.Based on the previous studies, this paper proposes a set of equations as a supplementary equation, the purpose of which is to give full play to the respective strengths of the photoelastic experiments and numerical methods, Together, solve the three-dimensional stress problem.
