The effect of various offaxis angles and lamina material properties on the shear modulus and the stress distribution of a circular cut-out in an orthotropic composite plate under shear loadings are presented. Based on the generalized Hooke's law, the generalized plane stress condition and the complex variable method, a dimensionless analysis is used to evaluate the influence of various elastic moduli E1, E2, G12 and ν12 on the laminate shear modulus and the stress distribution along the boundary of the circular cut-out within the laminate under shear loading. The results obtained from this dimensionless analysis provide a set of general design guidelines for structural laminates with high-precision requirements in engineering applications.
