Investigating strain localization at cracked concrete–sandstone specimens using optimized fractal theory-based image thresholding segmentation algorithm

The stability of concrete–rock interfaces is a critical issue in underground engineering. This study investigated the strain localization mechanism and energy evolution of concrete–sandstone specimens containing single and double interfacial cracks at various inclination angles. Acoustic emission (A...
