主 题:Finite L-shaped Mindlin plate Active power flow Reactive power flow Wave approach
摘 要:In this paper,wave and vibratory power transmission in a finite L-shaped Mindlin plate with two simply supported opposite edges are investigated using the wave *** 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 L-shaped plate,the near-field and far-field waves are entirely contained in the wave *** in-plane longitudinal and shear waves are also *** 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 *** influence of the plate thickness on the vibrational power flow is *** 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 L-shaped plate not only at high frequencies but also at low and medium ***,the effects of structural damping on the active and reactive power flow at the junction are also analyzed.
