Light weight thin alloys and composite materials have revolutionized aerospace, marine, electronics and construction industries. Based on their application and structural behaviour, plates are often designed in arbitrary shapes. This paper deals with free vibration analysis of simply supported plates with different geometries. The plates are modelled with a stiffener which is curvilinear in shape. To enable comparison of plates, three parameters viz., the area of plates, starting point of the stiffener and curvature of the stiffener were kept constant. The Finite Element model was developed for free vibration analysis using FEAST (Finite Element Analysis of Strctures). The geometries considered were circular, square, rectangular (with aspect ratio of 1.25, 1.50 and 1.75, respectively) and skew square (with 70o, 76.67o and 83.33o skew angles, respectively). It was observed that the stiffness increased with the increase in aspect ratio of bare plates unlike the case of stiffened plates. In the case of stiffened plates, the stiffness increased with increase in aspect ratio up to 1.50 and thereafter decreased for the aspect ratio of 1.75. The bare and stiffened plates showed an increase in stiffness with increase in skewness of the geometry. Among the geometries considered, the stiffener was found to be most effective for the circular plate (110% increase in stiffness compared to bare plate) and least effective for the rectangular plate (50% increase in stiffness compared to bare plate) with 1.75 aspect ratio. The rectangular plate with aspect ratio 1.75 had the maximum overall stiffness and the circular plate had the minimum overall stiffness in the case of bare plates. In the case of stiffened plates, skew plates with 70o skew angle had the maximum overall stiffness and the circular plate had the minimum overall stiffness.

Plates are being widely used for many structural applications such as aerospace, civil, electronic devices and marine industries etc. For these applications, it is important to know the plate behaviour under static loading condition. The present study focuses on filling the existing gap in the literature in order to know the plate behaviour of different geometrical shapes before and after adding the stiffener. A total of eight geometries namely circular, square, rectangular (with aspect ratio of 1.25, 1.50 and 1.75) and skew square (with 70o, 76.67o and 83.33o skew angles) were considered. Static analysis of considered geometries was carried out by using FEAST (a Finite Element software). To enable comparison of plates, three parameters namely the area of plates, starting point of the stiffener and curvature of the stiffener were kept constant. From the static analysis results, the effect of the curvilinear stiffener on different geometrical shapes, effect of aspect ratio on rectangular plates and effect of skew angle on skew square plates were given. The displacement of plates reduced significantly after adding the curvilinear stiffener to the bare plates and the stiffener was most effective in the case of circular plate. In the present study, the effect of aspect ratio and skew angle on static behaviour of bare and stiffened plates was also studied and discussed.
