Abstract
This paper describes the development of a Window-based framework for analyzing and visualizing two-dimensional stress field in digital photoelasticity. The program is implemented as stand-alone software. The program contains mainly two parts: computational part and visual part supplemented with several image-processing functions. The computation method used in the program for retrieval of photoelastic parameters (isoclinic and isochromatic parameters) is the phase stepping method. The visualization links between the results and the user by a gray scale or color map of such parameters, which is very convenient to the user for physical interpretation. With the Windows-based framework, additional modules either computation or visualization can be simply added to the program.
