Abstract

The Centre for Advanced Composite Materials brings together staff and students from the Departments of Mechanical Engineering, Polymer Science and Engineering Science at the University of Auckland. Research areas include development of new synthetic and bio-based composite materials, improved manufacturing technologies, and simulation and characterization of structural performance. Mark will give an overview of the Centre’s research areas, then describe a project related to the water slamming of hull panels for marine vessels. Controlled water slamming of composite hull panels was conducted in a unique servo-hydraulic test system to study the effect of hydro-elasticity for three panels with different stiffnesses. The experimental methodology successfully characterized the hydro-elastic behavior, which included kinematic as well as inertial effects. Hydro-elastic effects included significant changes in panel geometry, local velocity, fluid pressures, and panel structural responses. Results of the test programmed are compared to quasi-static and dynamic numerical analyses.

Biography

Dr. Battley completed his PhD at the Department of Mechanical Engineering at the University Auckland in 1993. He then worked as a composites research engineer at Industrial Research Limited (A New Zealand government research laboratory), and at the Department of Lightweight Structures, Royal Institute of Technology Stockholm, before joining the Centre for Advanced Composite Materials in 2006. His research interests include theoretical modelling and experimental characterization of polymer composite materials and structures, particularly failure mechanisms, design methodologies, dynamic behavior, and mechanical testing methods for materials and structures.
