Uniaxial Compression Mechanical Properties of Rock Samples ...

(1) When uniaxial compression occurs, the brittle tensile failure occurs in the composite stratum, and the strength is between the soft rock and hard rock. The strength of the hard rock is more than twice that of the soft rock, which indicates that the artificial composite formation could meet the requirements of strength difference.

Are rocks stronger under tension or compression? - R4 DN

Are rocks stronger under tension or compression? The tensile strength of rock is very small and is of the order of 0.1 times the compressive strength. Thus, a rock material is more likely to fail in tension than in compression. Why are most materials stronger in compression than in tension? tensile strength.
