Abstract: A method for determining virtually a set of design allowables for a composite material is disclosed. The method includes receiving information about the composite material and a given set of architectures, available test data of the composite material, and a test matrix identifying desired tests to be performed virtually on the composite material and different set of architectures. Using the material information and available test data, a reverse engineering process is used to determine micromechanical material properties. Finite element models of relevant test specimens are generated according to the test matrix and integrating the micromechanical material properties, and are analyzed. A set of allowables and associated properties is generated based on the finite element analyses results.
