ASTM E1820 Measurement of Fracture Toughness Test Fixture


ASTM E1820 test method encompasses ways and principles for the stabilization of crack rigidity of metallic substances by application of K, J, and CTOD parameters.

If the substance reaction couldn’t be foreseen before test, ASTM E1820 test is especially practical.

ASTM E1820 test method qualify its endurance to 4 different situation that considering the existence of sharp, preexistent, fatigue crack;

  • Fracture of a still crack
  • Fracture after constant tearing
  • Constant tearing beginning
  • Sustainable constant tearing
