Abstract
The growth of fatigue cracks in composites consisting of Al-4%Cu reinforced with strong tungsten wires has been studied during fully reversed tension/compression cycling of double edge-notched plates. The rate of crack growth dc/dN which is related to the range of stress intensity factor Delta K obeys the same power law which describes crack growth in a wide variety of materials, although the exponent is five rather than the theoretically predicted value of four. The stress intensity range for a given crack growth rate appears to vary with fibre volume fraction in the same way as the ordinary fracture toughness K which is determined in monotonic tensile tests on notched samples.
