When the angle β was constant, the p-value between the angle α and the maximum principal stress, the maximum principal strain, and fracture time.

Angle	The Maximum Principal Stress	The Maximum Principal Strain	Fracture Time
β = 0°	0.2315	0.1259	0.2013
β = 15°	0.075 *	0.0083 *	0.2312
β = 30°	0.1876	0.1974	0.2908
β = 45°	0.1565	0.2215	0.2561
