Predicting the uniaxial compressive strength and elasticity modulus of sandstones from physical and mechanical properties using statistical analyses and artificial intelligence-based techniques.

Dry unit weight (γ d ) and specific gravity (G s ) also show strong correlations with both UCS (R = 0.95 and 0.93 respectively) and Young’s modulus (E) (R = 0.97 and 0.95), while porosity (n e ) maintains slightly weaker but still highly significant relationships (R = 0.92 for both UCS and E).
