Size effect on damage evolution and failure characteristics of cyan sandstone under uniaxial compression

Abstract To investigate the influence of specimen size on damage evolution and failure behavior in cyan sandstone, uniaxial compression tests were conducted on cylindrical specimens with varying height-to-diameter (H/D) ratios (50 mm × 50 mm, 50 mm × 75 mm, 50 mm × 100 mm, 50 mm × 125 mm, and 50 mm ...
