    Strain Rate Effects on Characteristic Stresses and Dynamic Strength Criterion in Granite Under Triaxial Quasi-Static Compression by Lu Liu, Jinhui Ouyang, Wencheng Yang, Sijing Wang

    Published 2025-05-01
    “…The experimental results indicate the following: (1) crack damage stress (σ<sub>cd</sub>) and peak stress (σ<sub>p</sub>) show strong linear correlations with logarithmic strain rate, while crack initiation stress (σ<sub>ci</sub>) exhibits weaker rate dependence; (2) linear regression establishes characteristic stress ratios σ<sub>ci</sub> = 0.58σ<sub>p</sub> and σ<sub>cd</sub> = 0.85σ<sub>p</sub>; (3) macroscopic fractures transition from Y-shaped shear patterns under low confinement and strain rate conditions to X-shaped shear failures at higher confinement and strain rate; (4) the Mohr–Coulomb criterion effectively characterizes dynamic strength evolution in granite, with cohesion increasing 22% across tested strain rates while internal friction angle remains stable at around 50°; (5) variations in microcrack activity intensity during rock deformation stages result in the dynamic increase factor for characteristic stresses (CSDIF) of σ<sub>ci</sub> being lower than σ<sub>cd</sub> and σ<sub>p</sub>. …”
