Abstract Two traditional layups built from 0°/45°/90° plies and two recently proposed alternative non-traditional layups built from 5° /65° plies are analyzed in this paper. It was recently shown experimentally that using such off-axis plies in a composite laminate will result in a more damage tolerant structure. A cantilever beam with two traditional layup composite laminates and two non-traditional layup composite laminates is considered in this paper. Both traditional and non-traditional layup schemes are chosen such that they are "hard" laminates, i.e, much stiffer in the longitudinal direction than the lateral direction. The damage is simulated on the beams using a… More >
