摘要：

This paper presents a method to determine the four through-thickness stiffnesses of thick laminated composites. Only one specimen submitted to one test is required. The procedure is based on a suitable use of the principle of virtual work with four independent virtual fields. This leads to a system of four linear equations where the through-thickness stiffnesses are the unknowns. The system is finally inverted to determine the stiffnesses. Finite element simulations have been carried out to validate the approach and to show its stability.
