Abstract
Two experimental investigations have demonstrated the extreme usefulness of using wire strain gages in studying the mechanical behavior of com-posites. Wire strain gages have also shown their capacity in detecting some splitting failure types in notched composites under tensile loads. The first investigation entailed notched [07 8 unidirectional graphite/epoxy composites. An arrangement of wire strain gages around the notch boundary has easily detected the onset ofsplitting damage in the specimen. Splitting damage is through-the-thickness matrix cracks emanating from the notch tips and propagating along the filament direction. The second investigation entailed notched [0/145°Js graphite/epoxy laminates. Splitting damage in both the 0° and 45° plies have been identified using a modified gage arrangement.
