​Static and dynamic behaviour of trapezoidal cantilever plate are analysed in this work using ANSYS software. Static and dynamic analysis of trapezoidal cantilever plate has been carried out and studied the effect of change in taper ratio αt, aspect ratio a/b and varying tip to root width ratio c/b. It has been observed that at αt = 0.6 and c/b = 0.2, non-dimensional frequency of the trapezoidal cantilever plate is higher side, when both parameters varied. In bending analysis under uniformly distributed load when αt = 0.8 and c/b = 0.8 then tip deflection and stresses will be maximum, whereas under edge load when αt= 0.8 and c/b = 0.2 (smallest tip width) will have maximum deflection and stresses. Hence, present numerical results will be helpful for further researchers and designers to design safe thin-wall structures.
