Vibration, buckling and parametric instability behaviour of plates with centrally located cutouts subjected to in-plane edge loading (tension or compression)

摘要

The vibration, buckling and parametric instability behaviour of a plate with internal opening subjected to in-plane compressive or tensile periodic edge loading are studied. Different shapes and sizes of the cutout are considered. Compression and tension buckling results are discussed. The vibration Analysis for this problem shows that for certain parameters of tensile load, In and the opening, the frequency of the plate initially rises with the load, But then begins to decrease with increasing tension showing the onset of Tension buckling.
