Summary of calculation methods for the brittleness index.

Formula	Meaning of parameters
	B is the brittleness index; the lower number represents different representation; are peak stress and residual stress, respectively
	is the absolute deceleration after peak， that is,
	are failure strain and residual strain, respectively
	are maximum tangent modulus before and after peak
