A range of parameters associated with the waviness defect, including the waviness geometry, the ﬁber Composite laminates oﬀ-axis angle, the extent of wavy region and the waviness pattern, are incorporated into the analytical model. Stiﬀness The ﬁber volume fraction and the type of reinforcement are also taken into account in the parametric analysis. The three-dimensional stiﬀness parameters of thick wavy laminates are
