This paper addresses the narrow applicable fracture toughness range of master curve method (ASTM-E1921) by expanding scaling process to include effect constraint loss in miniaturized specimens. To facilitate acquisition and scalability reliable data from one specimen size another apply Master-Curve with confidence when using small specimens, difference structure crack tip stress field between l...

The characterization of the fracture toughness (KJc) ferritic steels in ductile-to-brittle transition (DBT) region, which is vital for analyzing structural integrity cracked structures subjected to large temperature changes, has been pursued by researchers and practitioners. This because KJc associated with a dependence (a change approximately 400% corresponding 100°C), specimen thickness (appr...

of the Thesis Optimizing Cache Behavior of Ray-Driven Volume Rendering Using Space-Filling Curves by Oleg Mishchenko Master of Science in Computer Science Stony Brook University 2006 We study the cache behavior of space-filling curves in the context of volume rendering with raycasting. An efficient bit-oriented algorithm for 3D Hilbert curve traversal is also proposed. We find that data organiz...

Abstract In this paper, the peak stress method (PSM) is adopted to analyse fatigue strength of steel welded joints. According method, a single design curve expressed in terms properly defined equivalent and it valid for arc-welded Private companies often need simple finite element beam models assessments, because large dimensions structures. However, elements provide nominal stresses (and not l...
