Abstract
A quantitative correlation has been established between the shift of the nuclear quadrupole resonance frequency of the tracer and the stress in a matrix-tracer system in composites. Measurements are made of the 63Cu resonance frequencies in samples of epoxy resin containing cuprous oxide powder. The stresses in the resin and their dependences on temperature and external pressure are determined.
