The present paper is concerned the effects of gravitational force and rotation in a composite multilayered hollow cylinder which contain inner and outer piezo-thermoelasticity layers bonded by Linear Elastic Material with Voids (LEMV) within the frame of dual-phase-lag model.Also the composite multilayered hollow cylinder coated with thin film is considered.The equation of displacement components, temperature, and electric are obtained using linear theory of elasticity. The dispersion equations are acquired by means of traction free boundary conditions and are numerically analyzed for CdSe material.The enumerated frequency, thermal and electrical nature against wave number in the presence of gravatity and rotation is presented graphically. Adhesive layer LEMV is compared with Carbon Fiber Reinforced Polymer (CFRP) in presence of gravity and rotation.
