Vibration Analysis of Laminated Composite Plate under Thermo- Mechanical Loading

The present study focused mainly on the vibration analysis of composite laminated plates subjected tothermal and mechanical loads or without any load (free vibration). Natural frequency dynamicresponse are analyzed by analytical, numerical experimental (by using impact hammer) fordifferent cases. investigation is to manufacture laminates find mechanicaland thermal properties glass-polyester such as longitudinal, transverse young modulus, shear modulus,longitudinal expansion conductivity. test carried tofind three natural frequencies plate. design parameters aspect ratio,thickness ratio, boundary conditions lamination angle were investigated classical laminatedplate theory (CLPT) Finite element coded ANSYS, in addition ofdynamic response type with respect time, x y dimension temperature value forsimply supported symmetric cross ply. main conclusion was could increaseand decrease depending conditions, thickness angle, aspectratio Present increase dynamic plate also onlamination temperature.
