This paper presents the main results of the numerical investigation on the shear behaviour of a composite sandwich primarily designed for naval engineering applications.
In fact, composite sandwich structures are preferred over many conventional materials in various industrial applications.
A comprehensive testing program has been performed to characterize the mechanical response of the sandwich panel and the constituent materials.
