Effects of a Weak Interlayer Zone on the Tensile Mechanical Properties and Failure Characteristics of Rock
Brazilian tests on limestone with weak interlayers (thickness 0.1–1.35 mm) were performed using RMT and 3D scanning. Results show that BTS decreases nonlinearly with increasing thickness and exhibits a complex angle dependence: fracture length and roughness first rise then peak at 30°, while microscopic features of r...
