Abstract
Microscopic observations have revealed [1] that fatigue cracks in unidirectional off-axis polymer-based composites initiate and grow within the matrix along a plane parallel to the fibre direction. The fatigue process is controlled by the microstresses on these critical planes as well as the properties of the matrix. Also, due to the fibre-matrix interaction a complex stress state occurs in the matrix resulting in a multiaxial stress state on the critical planes. A micromechanical stress analysis is conducted in the present study on unidirectional graphite/epoxy, boron/aluminum and glass/epoxy composites to calculate the local stress/strain fields which serve as a basis for determining a multiaxial stress/strain fatigue parameter used to correlate the fatigue life data and to derive a generalized fatigue stress/strain-life curve. This curve is then used to predict the fatigue lives of the particular composite tested under a variety of loading conditions.
