Flexural strength is defined as three points of flexural test.
  • D = 3FL/2bh3. D is flexural strength,
  • F is maxmum load,
  • L is distance of fulcrum to fulcrum,
  • b is sample width
  • h is sample thickness.
  • The unit of Young's modulus, flexural modulus and flexural strength is MPa
  • Flexural modulus is defined as three points of flexural test.
    • E = L3F/4bh3Y. E is flexural modulus,
    • L is distance of fulcrum to fulcrum,
    • b is sample width,
    • h is sample thickness,
    • F is load at linear part and Y is flexure at F.
