Identification of the through-thickness properties of thick laminated tubes using the virtual fields method
Identification of the through-thickness properties of thick laminated tubes using the virtual fields method
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.

Abstract
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.
