The Size-dependence of Plane Strain Fracture Toughness: A Mechanistic Analysis by Enforcing Constant Crack Tip Fracture Stress and Scaling Laws

Abstract Experimental measurements of plane strain fracture toughness, made using single-edge-notched-bend (SENB) specimens, show strong crack (or ligament) size and specimen size effects on toughness. The fracture toughness varies strongly with crack size even at relatively smal...
