Abstract

This undergraduate research project proposes the development and computational implementation of a non-linear aeroelastic model for supersonic panel flutter based on first-order piston theory for the aerodynamic forces and the von Kármán non-linear strain measure for plates. The Finite Element Method will be employed to solve the problem through time-domain simulation. There is intention of doing research abroad through the BEPE exchange programme in the University of Porto with the goal of including the mechanical behaviour of laminated composites to the computational model.
