Abstract
In a world without borders, which aircraft is one of important transportation to travel anywhere, with low cost, less time and need energy. Nowadays, engineer study and make observation about dynamic behaviour of thin isotropic rectangular plates due to the safety of aircraft. In aerospace vehicles, lightweight material also one of the important characteristic due to the industrial needed which can reduce many materials and costing. However, as all known, the structure of light weight plate always very thin and the material is high modulus young which can produce to the unused high vibration. This research presents about vibration analysis for a thin isotropic plate containing an arbitrarily orientated surface crack. The content of this research activity is about the significantly enhanced crack model within the analytical model of the plate, in modal space, and taking the form of a specialised Duffing equation. To represent the vibrational response of the plate,the governing equation of motion of the healthy plate model with enhanced crack modelling is proposed based on Classical Plate Theory into which a developed crack model has been developed. The formulation of the angled crack is based on a simplified linespring model, and the cracked plate is subjected to transverse harmonic excitation with arbitrarily chosen boundary conditions.The results from this thesis show that there is changes between healthy plate and cracked plate.The angle of cracked plate show the different neutral frequency obtain by final equation of cracked plate.
