Thermal Loading in the Laser Holography Nondestructive Testing of a Composite Structure.

Abstract

A unique laser holographic interferometry method that has variable sensitivity to surface deformation has been applied to the investigation of composite test samples under thermal loading. These experimental results are presented along with the mathematical analysis of the physical model of the thermal loading and current conduction in the composite material. (AN)
