... estimation, fracture test, ASTM E1820 INTRODUCTION Fracture toughness is a measure of capability of a ductile material to resist fracture. It can be a single point value to use for describing the onset of stable fracture tearing; or a resistance curve to use for describing the material resistance during...

... efforts of investigations have been made to develop its experimental estimation method, testing technique and standardization, as evident in the ASTM E1820 — a commonly used fracture toughness testing standard. In recent years, significant progresses of the J -integral fracture testing and experimental...

... fracture test data for HY80 steel. The results show that the proposed incremental J- integral equation can obtain much improved results of J-R curves for larger crack growth increments, and thus is more accurate than the present ASTM E1820 equation.
