RISElastic-Plastic Deformation in Edge-Notched Tension Specimens Under Plane Stress Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An elastic-plastic, plane stress, finite element analysis has been performed on edge-notched tension members having elastic stress concentration factors of 2.28 and 3.06. For net section stresses ...
Elastic-Plastic Fracture Toughness: A Comparison of J-Integral and Crack Opening Displacement Characterizations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The geometry dependence of the J-integral and crack opening displacement at fracture initiation, Ji and (COD)i , is examined for HY-80 steel using precracked bend specimens having thicknesses ...
Initial Crack Extension in Two Intermediate-Strength Aluminum Alloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-point bend tests were conducted to examine the geometry dependence of JIc in two intermediate-strength aluminum alloys, 2024-T351 and 7005-T6351. The amounts of crack growth at selected ...
The Cracking of Ti-6Al-4V Alloys Under Sustained Load in Ambient Air
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study reveals that degradation in load-carrying capacity owing to sustained-load cracking (SLC) can occur in alloys of the Ti-6Al-4V family. Each of eight alloys tested with fatigue-precracked ...
