The purpose of this study was to determine the fracture toughness (K(IC)) of human dentin and to test the null hypothesis that K(IC) is not affected by the orientation of dentinal tubules relative to the plane of crack propagation. Triangular prisms (4 x 4 x 4 x 8 mm) were obtained from human molars

## Abstract The __in vitro__ fracture toughness of human dentin has been reported to be of the order of 3 MPa√m. This result, however, is based on a single study for a single orientation, and furthermore involves notched, rather than fatigue precracked, test samples. The present study seeks to obta
The fracture toughness of an epoxy-based film adhesive has been investigated using Mode I and combined Mode 1 + Mode II loadings. The opening Mode, Mode I, was realized by employing the Tapered Double Cantilever Beam (TDCB) specimen, while the mixed opening and shear modes, Mode I + Mode II, resulte
