A two-dimensional weight function approach is used to determine stress intensity factors for cracks in either tensile or compressive stress fields, due to one of three mechanisms: remote tension overload, remote compression overload or hole cold expansion.

This report describes the development of a Thermal Wave Interferometry (TWI) system for the characterisation of film thickness. The capability addresses the need for a method to assess bondline uniformity for the compact multi-parameter load evaluation (CMPLE ) device, a low-cost surface-mounted sensor package with an in-flight strain measurement capability.

DSTO, in collaboration with DNPS, have undertaken a series of calm water resistance scaled model tests on the Armidale Class Patrol Boat, (ACPB) to deveop a database set for validation studies.

A critical review of the available literature concerning the minimum reliably detectable defect size aNDI for magnetic particle testing (MPT) in aerospace applications is presented.
