Abstract

The influence of the stress direction on the ambient temperature tensile properties of a lamellar Al-CuAl2 eutectic composite is investigated using metallographic observation and tridirectional extensometry. Noncoincidence between stress and strain principal directions is pointed out and studied. Deformation leading to failure may occur by three different modes according to the value of the angle between the tension direction and the plane of the lamellae. The model of failure proposed by Kelly for fibrous composites is adapted to the case of lamellar composites. It accounts for the variation of the ultimate tensile strength with the tension direction.
