Assessment of the fracture behavior of an asymmetrically loaded cantilever composite structure

Article Abstract:

The complex fracture behavior of a cross-ply composite cantilever beam with artificially embedded delamination is investigated analytically, numerically and experimentally. All numerical, analytical and experimental results illustrate that the fracture behavior of the laminate cantilever beam is dominated by mode II, mainly due to the effect of a large contact zone which makes the structure stronger in resistance to deformation, although the effects of the delamination should not be neglected.

On the energy release rate of fatigued composites subjected to compressive overloads

Article Abstract:

The variable amplitude compressive testing of graphite/epoxy composite laminates reveals that the delamination growth is slower when plies within a specimen align in the load direction. Data indicate that the energy release rate reduces with the increase in the delamination length, which in turn diminishes the overloads effect.
