This chapter describes a 'super' element as an alternative to conventional solid elements when analyzing scarf joint and scarf repair configurations in composite panels. The super element, which consists of a higher-order plate element for the adherends and a linear solid element for the adhesive, eliminates through-thickness discretization while providing complete three-dimensional stress and strain fields without constraints on the nature of the lamination and type of loading. The higher-order nature of the plate theory makes it suitable for analyzing thick laminates and sandwich panels comprised of numerous plies. This approach can support the design, analysis and verification testing of composite panels with unrepaired damage and a parametric range of scarf repair configurations with external patches.
