Conclusion

Inclined exposure to radiation, coupled with measurement of the intensity of light fluxes transmitted in the forward direction and reflected from crazes and subsequent interpretation of the results of the measurements using a model that assumes one-time reflection and the presence of a certain functional dependence of the refractive index of the craze along its length, is the most effective of the optical methods that we examined for the investigation of the damage sustained by transparent polymers prone to craze formation. Based on a series of similar analyses, it is possible to evaluate the variation in such craze parameters as total length, form, and degree of loosening in the fatigue process.
