Characterization of Stable Delamination Growth in Fiber-reinforced Polymers using Analytical and Numerical approaches
DownloadSpring 2013
A new test method, named internal-notched-flexure (INF) test, has recently been proposed to quantify mode II interlaminar fracture toughness of fibre composites. Previous investigation has shown that unlike any of the existing test methods, the INF test generates unconditionally stable...

Effects of Submerged Arc Weld (SAW) Parameters on Bead Geometry and Notch-Toughness for X70 and X80 Linepipe Steels
DownloadFall 2009
For the manufacture of higher strength pipelines to be feasible, a better understanding of the effects of welding on toughness is necessary. Bevel submerged arc welds were performed on X80 grade steel. The subsequent Charpy V-notch (CVN) test results indicated that the notch placement in the...
