Experimental Study on the Tensile Properties of Rock-Mortar Interface under Different Strain Rates by Nan Wu, Zhende Zhu, Zhilei He

“…In this paper, an experimental study was carried out on a rock-mortar interface specimen under three different strain rates (10−6, 10−5, and 10−4  s−1) using the MTS322 electrohydraulic servo loading system, and a new constitutive relation function of fictitious crack model (FCM) according to the axial-stress-crack-width curves of the rock-mortar interface is established, because the traditional nonlinear softening function easily distorts, shakes, and so cannot describe the damage-evolution process of the rock-mortar interface accurately. …”

Mechanical Characterization of Unsaturated Loess and Numerical Simulation of Slope Stability Under Freeze–Thaw Cycles by Gang Wei, Jianyu Xiao, Yuanbing Xia, Weiheng Peng, Xinning Wu, Huijuan A, Huawen Qi, Zhilin Ren

“…The findings indicate that (1) the stress–strain curves from both tests typically exhibit weak strain-softening behavior, with increased matric suction enhancing shear strength; (2) in the direct shear test, both cohesion (c) and the angle of internal friction (φ) rise with matric suction, whereas in the triaxial test, cohesion increases while φ decreases; and (3) an increase in freeze–thaw cycles results in a gradual decline in slope safety factor, though the rate of decline diminishes over time. …”
