Thermoviscoelastic response of fiber-reinforced-plastic laminates with initial deflection imperfection

摘要

The viscoelastic behaviors of simply supported cross-ply and angle-ply laminates, having various magnitudes of imperfections, and, subject to instantaneous temperature rise, are examined. Each viscoelastic lamina is taken to be a thermorheologically simple material. The analysis is based on the von Karman assumption and the first-order shear deformation theory. The stress function and the angles of rotation are obtained separately from the compatibility equation and from the moment equilibrium equations using the Laplace transform.
