    Abstract

    Non-linear finite element analyses provide some insight into the mechanical behaviour of four different double-lap anchor configurations for composite laminates. The studies indicate that parabolically varying anchor plates with horizontal tangents at the front end provide superior performance compared to all other configurations examined, including the commonly used anchors in laboratory studies. Performance is quantified here in terms of the maximum shear stress in the adhesive layer, which is typically the critical factor in the strength of such anchors. Through parametric studies it is also concluded that the performance of the optimum parabolically varying anchors can be improved by reducing the front end plate thickness as much as practically possible, while increasing the adhesive thickness and the presence of a confinement is also favourable.
