The Influence of Loading Rate on Direct and Indirect Tensile Strengths: Laboratory and Numerical Methods

Figure 4

Typical failures after indirect tests: (a–e) rock failures at the loading rates of 0.01, 0.05, 0.1, 1, and 10 mm/min, respectively, for the BT tests; (f–j), (k–o), and (p–t) FBT tests with the loading angles of 5°, 10°, and 15°, respectively.
