Flexural strength
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
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.
