Comprehensive Study of Free Vibration of Rectangular Mindlin’s Plates with Rotationally Constrained Edges Using Dynamic Timoshenko Trial Functions
(i) single frequencies, (ii) repeated frequencies (identical twins) and (iii) non-repeated frequencies (fraternal twins). Plates with different rectangular aspect ratios have been also analysed to show the deviation in the frequencies and mode shapes from the square plate. Also, their asymptotic behaviour to the corresponding Timoshenko beam at extreme aspect ratios has been established.
