Dynamic Splitting Tensile Properties and Failure Mechanism of Layered Slate

Table 4

The relationship between bedding inclination angle β and tensile strength σ and dynamic elastic modulus E (I;is the loading rate about 240 GPa/s; II is the loading rate about 600 GPa/s).

Loading rate type	Sample no.	Inclination angles (°)	Loading rate (GPa/s)	Failure load (MPa)	Dynamic elastic modulus E (GPa)	Indicator trend
I	A-3	0	273	11.50	34.56
	E-1	15	242	10.79	34.53
	B-6	45	291	12.00	52.86
II	A-1	0	587	15.55	41.76
	E-3	15	606	17.05	90.36
	C-7	60	561	18.98	133.29
	G-2	75	599	20.60	154.86
	D-2	90	601	21.21	136.86
