This paper presents a method to predict the design allowable for composite laminates subjected to a tensile load with finite element analysis. The mechanical properties were obtained by conducting tensile and compressive lamina tests. The statistically-based properties were acquired using an in-house tool to calculate the design allowable. A tensile load was imposed on the FE model of the laminate, and each ply stress was compared to the design allowable of the lamina test. The load was considered as the failure load when the ply stress reached the allowable value. This load was applied to a laminate model to perform finite element analysis, and the laminate strength was calculated. The calculated strength and design allowable of the laminate were compared, and as a result, the difference between the results of analysis and test was found to be within 10%.
