Abstract
The acoustic emission signature of VDS (variable depth sonar) tow cable was acquired to permit evaluation of the feasibility of having a continuous monitor of cable integrity and an indication of remaining life in cycles of load before rupture. The acoustic emission system at DREP (Defence Research Establishment Pacific) and the nature of VDS cable failure are described. The acoustic emission signature revealed that the degree of fatigue damage and an estimate of the number of broken strands in the cable could be determined from the amplitude distribution of AE signals occurring during the cable life. The design and use of a monitor based on this information is outlined.
