Abstract

There remains a question about the reliability of the crack growth resistance curves of continuous fibre-reinforced composite materials, because of uncertainties about the crack growth increments. It is now well known that when the dimensions of the fracture specimen are the same order as the macrostructure of the material, the R-curve behaviour is greatly affected by the presence of a process zone in front of the crack (Sakai, 1988) and to the eventual bridging zone along the crack (Fourve1,1989). Theoretical or semi-empirical methods have been developed to fit-up such behaviours to the frame of Linear Elastic Fracture Mechanics (Sakai et al., 1983; Shah, 1984; Mai et al., 1984, Swain, 1986). But whatever the method used for the investigation of the crack growth resistance behaviour, one needs crack lengths values along the loading curve.
