✦ Synopsis

Equations of motion for antisymmetric angle-ply plates in a general state of non-uniform initial stresses, where the effects of transverse shear and rotatory inertia are included, are derived by using Trefftz equations and the variational principle. These equations are then non-dimensionalized to a generic form by introducing global constants in orthotropic space and properly rearranging on-axis to off-axis stiffness relations for angle-ply laminates. Finally, the stability and vibration equations are solved for simply supported rectangular plates in a state of normal stress plus an edge twisting stress. The effects of twisting and the global material constants on the buckling and vibration of plates are studied.

Three groups of elastic constants, defined as orthotropic constants, have been introduced in this paper, and utilizing these constants enables the transformed stiffness to be expressed in rather simple forms. To simulate spatial fiber orientation in a preferred direction, a distribution function con
