ABSTRACT:
Photoelastic elements are formed deliberately with stress concentrations so that, when evaluated with a polariscope, more pronounced isochromatic bands or fringes result when loads are applied to these elements or to assemblies of these elements. A toy for producing color patterns and having polarizing filters coupled to frame elements is disclosed.
