In this paper, the damaged area in fibre-reinforced quasi-isotropic laminates that have been subjected to low-velocity impact is treated as a circular inhomogeneity in a finite plane region. The modulus of the damaged area is estimated using a self-consistent model, together with the solution for the inhomogeneity problem and experimental data. The post-impact compressive strength of the laminates is then predicted using the inhomogeneity model. The predicted post-impact compressive strength is shown to be in good agreement with experimental results for the considered quasi-isotropic laminates of two thicknesses.
