DYNAMIC STABILITY OF EDGE CREAKED PLATES

This paper presents a finite element study on the vibration, buckling and dynamic stability behaviour of a cracked plate subject to an in plane compressive / tensile periodic edge load. The effects of crack length and orientation are analysed. Under tension load, the results show that the frequency of the plate increases with the load. The size and the orientation of the crack and the loading parameter can all have a significant effect on the dynamic stability behaviour of the plate under both compressive and tensile loading. The effects of these parameters are discussed.
