Structural modeling of manufacture-induced gaps and overlaps by high-order unified finite elements

Abstract. Variable stiffness composites present additional tailoring capabilities if compared to classical straight fiber composites. However, the fabrication of these advanced leads inevitably presence manufacturing signatures such as gaps and overlaps, which alter mechanical behavior laminated components. In this work, fundamental frequency variable laminates with overlaps is studied. The Defect Layer Method considered for modeling defects, while Carrera Unified Formulation employed derive governing equations will be solved by Finite Element Method.
