Abstract	The results are reported of mixed-mode-fracture tests on CLWL-DCB (cracked-line wedge-loaded, double-cantilever-beam) specimens additional to those of Kobayashi et al (1985), and finite-element evaluations of those results are made using the mode I FPZ (fracture-process zone) model of Liaw et al (1990). Based on the semiempirical results reported by earlier workers, the effects of shear transfer on predictions of those mixed-mode concrete-fracture results are also examined. The study results are discussed, and it is demonstrated that the FPZ model, orignally developed for mode I concrete fracture, can also be used to characterize mixed-mode concrete fracture as long as the crack trajectory is straight. Combined with an appropriate shear-transfer model, it can predict accurately the maximim load-carrying capacity and postfracture behavior of concrete specimens in which the cracks curve under mixed mode loading.
