Coating for thermoelasticity and for photoelasticity

摘要

An epoxy resin coating, which is "black" in the infra-red part of the spectrum is not only used in reflection photoelasticity to evaluate stress but also as a coating on a surface of body to be subjected to cyclic loading and examined by thermoelasticity using an infra-red detector also to evaluate stress. The coating enables thermoelasticity and photoelasticity to be observed simultaneously.
