Physical and mechanical properties of different minerals in the synthetic granite (from reference [34]) and the steel bar.

Mineral Type (Bar)	Density (g/cm3)	Elastic Modulus E and (K, G) 1 (GPa)	Poisson’s Ratio
K-feldspar	2.56	69.8 (53.7, 27.2)	0.28
Quartz	2.65	94.5 (37, 44)	0.08
Plagioclase	2.63	88.1 (50.8, 29.3)	0.26
Biotite	3.05	33.8 (41.1, 12.4)	0.36
Steel bar	7.90	184.4 (140, 72)	0.28

¹K—bulk modulus; G—shear modulus.
