Moving load analysis on cross/angle-ply laminated composite nanoplates resting on viscoelastic foundation

In this research contribution, size-dependent forced vibration analysis of embedded cross/angle-plies laminated composite nanoplate in a viscoelastic foundation while subjected to a moving load is investigated. Through Hamiltonian principle, the governing motion equations are derived on the basis of a four-variable refined higher-order shear deformation theory (RHSDT) in Cartesian coordinate and Eringen nonlocal differential model (ENDM) is used in order to predict the size-dependent effects. Afterwards, in order to solve the equations, a time-dependent system of state-space in conjunction with an analytical solution method is implemented over the structures. For the first time, the effect of lay-up numbers and sequences, fiber orientations of involved layers, elastic/viscoelastic foundation coefficients, and nanoplate geometries on the size-dependent dynamic response of laminated composite nanoplate under moving concentrated load with different values of velocity and time history is examined.
