Abstract

There is a great demand for optimization of high performance composite structures, particularly in the aerospace sector. To avoid vibrational resonance in aerospace and naval structures, laminated plates can be designed using fundamental frequency constraints. Composite panels are particularly attractive because the vibration response can be optimised by tailoring the fibre angles of different layers without incurring weight penalties. A viable alternative is to use circumferential and radial layers for optimizing fundamental frequencies. This work focuses on the application these two types of theoretical layers and investigating its efficiency, for plates with and without cutouts.
