Shear bands in stressed polycarbonate
Yielding in glassy polymers often proceeds by a small sheared region propagating through the material. These patterns can be used in the stress analysis of fracture processes. In addition, the colours in the image are the result of birefringence and relate to the strain-induced alignment of the polycarbonate molecules. Because the specimen is below the glass transition temperature of PC (145 °C), the material will relax when the stress is removed and there will be no residual alignment.
