| Abstract: | This paper treats the analysis of a laminate strip with a circular hole. Useful approximate expressions （7）, （12） and （14） for the distributions of net section normal stress and the stress concentration factor are derived by means of an approximate approach. The expressions are applied to the computation of laminate strips with a circular hole. The numerical computations performed are compared with the available test data and the finite element calculations. It is verified that the expressions are satisfactory. |
