Identification of the through-thickness moduli of thick composites from whole-field measurements using the Iosipescu fixture: theory and simulations

Record type: Article

This paper presents a method to measure the four through-thickness moduli of a thick coupon subjected to a shear-bending load obtained with the Iosipescu fixture. The identification method relies on the global equilibrium of the specimen written with the principle of virtual work with different virtual fields. It requires the measurements of the in-plane strains over the whole surface of the specimen. The choice of a set of virtual fields is presented and validated using finite element simulated measurements. The stability of the method is checked by adding simulated experimental noise. The stability is found to be compatible with experimental implementation except for Poisson's ratio.
