A methodology for the viscoelastic analysis of filament-wound polymer matrix composites is developed and demonstrated. The procedure uses the elastic- viscoelastic correspondence principle with standard micromechanics models to obtain the viscoelastic properties of the composite. For global analysis, an efficient time-stepping algorithm is developed and implemented in a general purpose finite element code via a user-supplied material subroutine. The algorithm is verified by comparison to the exact analysis of a rigid inclusion in an infinite viscoelastic plate and the utility of the entire methodology is shown by analysis and testing of a composite spring.
