Paper Abstract

The equations relating the output of the SPATE* 8000 thermoelastic stress analysis system to the strains in multidirectional laminated fibre composites have been developed. The system has been calibrated for use with a particular carbon fibre/epoxy resin material. For multidirectional laminates under a generalised state of stress, it has been observed that the sensitivity of the SPATE output to the various strain components differs significantly such that even the qualitative interpretation of SPATE scans is difficult. However, there are a number of special cases which are applicable to practical structural laminates for which the interpretation of scans is greatly simplified.
