Research studies to determine the effects of vibration and fatigue on structures and components, using practical dynamic and static structural analysis methods/techniques or employing finite element analysis and other computerised simulation techniques to understand the response of structures to a variety of conjoint mechanical environment influences. Analysis and evaluations of fracture mechanics, and fracture resistance as applied to airworthiness and other safety issues. Also includes work to exploit life extension technology. Also includes research supporting determinations of static, dynamic and hydrodynamic performance of marine structures, and the structural design of land vehicles, and marine platforms, especially those, which may undergo explosive loadings. Also includes research to aid the assessments of design options for and safety margins of future military satellites. Also includes research in the fields of aeroelasticity, hydroelasticity and structural dynamics and structural acoustics. Also includes supporting work to aid structural integrity studies.
