A constitutive model for composite materials based on the mixing theory is used to predict their behaviour under cyclic loads. This model permits that each constituent has anisotropic properties with different no-lineal constitutive laws. Moreover, a residual strength evolution law associated to each constituent permits to determine the degradation and the fatigue life of the composite under cyclic loads with variable amplitude.
