    A simulation model of the viscoelastic/damage response of a filament-wound cylindrical pressure vessel to proof-test loading is developed. The matrix material of the composite system is assumed to be linearly viscoelastic. A damage model based upon a quadratic relationship between the transverse modulus and maximum circumferential strain is proposed. The resulting nonlinear model is solved by an iterative routine based upon a reduced stiffness. The elastic-viscoelastic correspondence principle is used to produce, in the Laplace domain, an associated elastic solution for the maximum circumferential strain which is inverted by the method of collocation to yield a time-dependent solution for each iteration. A numerical example is included to demonstrate the application of the simulation model.
