Application of Work Factor to Determine Fracture Toughness of Unidirectional Graphite/Epoxy Composites under Hydrostatic Pressure

정수압을 받는 일방향 탄소섬유/에폭시 복합재의 파괴인성 결정을 위한 일인자 적용

In this paper. tile validity of work factor approach was investigated to determine compressive fracture toughness of unidirectional graphite/epoxy composites under hydrostatic pressure environment. The elastic work factor was determined under various pressures as a function of delamination length. It was found that elastic work factor was not affected by hydrostatic pressure.
