Experimental and analytical results are presented for the post-failure behavior of quasi-isotropic glass-epoxy laminates with a central circular hole. Load-strain response is predicted by combining a failure model developed from tests of unnotched laminates with a tangent-modulus finite-element analysis of the notched laminate. The prediction is shown to agree both qualitatively and quantitatively with experimental results.
