Abstract
The problem of stress concentrations in the area of pin-loaded holes is of particular significance in the design of multilayered fibre-reinforced composite structures. For the purpose of simulating such problem zones in anisotropic multilayered composites, analytical methods offer decisive advantages since they, in comparison to numerical methods, allow weighting of influencing parameters and in this way permit a physical interpretation of complicated notch phenomena. At the Institut für Leichtbau und Kunststofftechnik (ILK) sophisticated analytical solution methods for the stress concentration problem in multilayered composites with pin-loaded holes were developed on the basis of layer-related solutions and have been confirmed in numerical calculations.
