ON THE METHOD FOR STRESS ANALYSIS IN PHOTO-ORTHOTROPIC ELASTICITY

摘要

摘要: 本文建立了正交异性光弹性应力分析的实验边界元混合解法并编制了相应的程序系统BE-MSC.该方法仅需模型边界结点处等差线一项实验数据即可实施应力的分离。它还十分适用于存在初应力的模型材料光弹性分析问题。最后对正交异性对径受压圆盘进行了光弹性应力实例分析。

Abstract: A combined method of experiment-boundary element is suggested for stress analysis in photo-orthotropic-elasticity, and a corresponding program system BEMSC is developed. One item experimend ata(isochromatic line) is only needed by applying the method. It is also applicable to the problem of photo-orthotropic-elastic analysis for the modd m at erials with residual stresses. An example of stress analysis is given in photo-orthotropic-elasticity.
