摘要：

The effects of different configurations of echelon crack on the crack propagation mechanism in the gypsum samples with different lengths and crack inclination angles under the uniaxial compressive loading condition were studied. These samples were explicitly prepared in the laboratory and tested uniaxially under compression. Bridge areas were specified by considering the 2 cm distance between the cracks. These samples contained echelon cracks with varying inclination angles of 0 degrees, 30 degrees, 60 degrees, and 90 degrees. Therefore, twelve samples with different configurations were provided and tested to investigate the effects of echelon cracks on the crack extension mechanisms of the rock-like materials under compression. These two sets of results provided an accurate and robust methodology for studying the crack extension mechanism of the rock-like materials.
