Abstract

The use of infra-red techniques for full field stress analysis has increased rapidly in the last two or three years, due mainly to the introduction of a production model of the SPATE (Stress Pattern Analysis by Thermal Emission) equipment, developed by Sira Ltd. The Sira technique makes use of the thermoelastic effect by measuring the very small temperature changes which occur when structures are cyclically loaded. This paper describes the investigation of structures under broad-band random loading, using a standard SPATE 8000 together with an add-on hardware/software system developed for this purpose at the National Engineering Laboratory.
