Fracture toughness of fiber reinforced composites under transverse loading
- The debonding of a fiber in a glass fiber / epoxy composite under transverse loading is analysed. The stress field in the interface as well as the energy release rate are analysed for various fiber volume fractions between 5% and 85%. The circumferential propagation of an interface crack in a hexagonal fiber array is studied. The analysis is performed by a finite element simulation under plane stress conditions. The stress distribution during crack propagation is calculated for different crack phases. The crack starts under dominating mode I stresses. After propagating some 60° the mode II part reaches a maximum while the mode I part vanishes and the crack closes. The further crack propagation is driven by mode II stresses only. In addition, the stress transfer into the neighbouring fibers during debonding is studied.
