摘要：

The viscoelastic response of laminated composites under the influence of mechanical and hygrothermal loads is studied analytically. A finite element formulation is developed for the thermo-viscoelastic solution of free edge stresses in composite laminates. Numerical results are obtained to verify the present finite element approach and to demonstrate the viscoelastic effect in graphite epoxy composites. In addition, the effect of laminate orientations and environmental conditions on the interlaminar stress distributions and histories is presented. © 1990.
