โœฆ Synopsis

A finite element approach based on the Hermitian ZigZag theory and on the sub-laminates concept is proposed for the static analysis of sandwich structures. The accuracy of the model is evaluated through a set of numerical results about the static response of sandwich beams with composite multilayered faces subjected to different boundary conditions and external loads; a comparison with three-dimensional exact elasticity solutions (when available) and high-fidelity FE models is also performed. An experimental tests campaign is also carried out to further assess the HZZ model accuracy. It is shown that the proposed approach is valid in determining global and local responses of sandwich beams.

A new finite element (FE) model has been developed based on higher order zigzag theory (HOZT) for the static analysis of laminated sandwich beam with soft core. In this theory, the in-plane displacement variation is considered to be cubic for both the face sheets and the core. The transverse displac
