Abstract
In this paper wave and vibratory power transmission in a finite Lshaped Mindlin plate with two simply supported opposite edges are investigated using the wave approach The dynamic responses active and reactive power flow in the finite plate are calculated by the Mindlin plate theory MPT and classic plate theory CPT To satisfy the boundary conditions and continuous conditions at the coupled junction of the finite Lshaped plate the nearfield and farfield waves are entirely contained in the wave approach The inplane longitudinal and shear waves are also considered The results indicate that the vibratory power flow based on the MPT is different from that based on the CPT not only at high frequencies but also at low and medium frequencies The influence of the plate thickness on the vibrational power flow is investigated From the results it is seen that the shear and rotary inertia correction of the MPT can influence the active and reactive power at the junction of the Lshaped plate not only at high frequencies but also at low and medium frequencies Furthermore the effects of structural damping on the active and reactive power flow at the junction are also analyzed
