Abstract
This paper investigates the effect of temperature on the basic characteristics (i.e. peak levels, ring-down counts, and energies) of acoustic emission (AE) signals in metallic structures. The experimental AE data were acquired from a series of pencil-lead breakage (PLB) tests performed on a steel plate for two temperature values, i.e. 30°C and 70°C. The temperature influence was introduced by placing the test specimen in a controlled environmental chamber. The results have demonstrated the strong influence of temperature conditions on all characteristics of AE signals.
