Marginal fracture toughness of composite resins.
The marginal fracture toughness of several types of composite resins was determined by means of the rattler test. Microparticle-filled resins showed significantly higher marginal fracture toughness than conventional composites. Posterior restorative composites were intermediate between MFRs and conventional composites. Amalgams were inferior to restorative resins. These data correspond with the...
متن کاملFracture toughness of composite and unfilled restorative resins.
Fracture toughness, critical strain energy release rate, and critical stress intensity factor were determined for experimental and commercial restorative resins. A composite resin had lower resistance to crack initiation than an unfilled acrylic resin. The data were consistent with surface failure observed in single-pass wear studies of these resins.
متن کاملOn the velocity-dependent fracture toughness of epoxy resins
In a recent paper [1], Drs Selby and Miller described three methods of determining the fracture toughness (R), or equivalently, the fracture surface energy (23') for an epoxy resin. These methods are respectively (a) Berry's method, (b) Irwin-Kies equation and (c) Gurney's irreversible work area method. While the experimental data obtained from tapered double-cantilever beam (TDCB) specimens su...
متن کاملDislocation-Governed Plastic Deformation and Fracture Toughness of Nanotwinned Magnesium
In this work, the plastic deformation mechanisms responsible for mechanical properties and fracture toughness in nanotwinned (NT) magnesium is studied by molecular dynamics (MD) simulation. The influence of twin boundary (TBs) spacing and crack position on deformation behaviors are investigated. The microstructure evolution at the crack tip are not exactly the same for the left edge crack (LEC)...
متن کاملFracture and fracture toughness of nanopolycrystalline metals produced by severe plastic deformation
The knowledge of the fracture of bulk metallic materials developed in the last 50 years is mostly based on materials having grain sizes, d, in the range of some micrometres up to several hundred micrometres regarding the possibilities of classical metallurgical methods. Nowadays, novel techniques provide access to much smaller grain sizes, where severe plastic deformation (SPD) is one of the mo...
