Abstract
The creep behavior of continuous fiber reinforced unidirectional composites due to the viscoelasticity of the resin matrix is analyzed based on the homogenization theory utilizing the finite element method. It is assumed that the constituent fiber is transversely isotropic linearly elastic material and that the matrix is isotropic linearly elastic and nonlinearly viscoelastic. The theoretical predictions for the creep behavior of the composites are compared with the experimental results.
