An empirical Three Stage Initiation-Propagation (TSIP) model has been developed which predicts the fatigue resistance of tensile-shear spot welds under constant amplitude loading test. The TSIP model consists of Stage ...

Rapid solidification processing (RSP) has been used to produce extended solid solutions of rare earth elements and O in Ti, and some of its alloys. RSP has been effected by laser surface melting and the resulting microstructures ...

Kinetics of crack propagation in hydrogen charged niobium were studied in the temperature range 77 to 303 K and for hydrogen concentrations between 0.068 and 3.2 at.%. Crack velocities between 10('-8) and 10('-2) m/s were ...

The dynamics of entangled polymer melts have been examined using polarized Fourier-Transform infrared (FT-IR) spectroscopy. Based on the reptation model, the motion of a chain in the presence of topological entanglements ...

Cruciform joints were fatigue tested under SAE Bracket variable loading history. Tube-to-plate welds were fatigue tested under bending and torsion loading conditions. Fatigue test results were compared with predictions ...

Cu-Cr metastable alloys are interesting both from a basic science viewpoint (i.e., alloy theory for elements with very limited mutual liquid and solid solubilities) and from a technological viewpoint (i.e., "stainless" ...
