DOI: 10.1007/s00603-018-1417-1
Abstract: The strength and deformation characteristics of rocks are the most important mechanical properties for rock engineering constructions. A new nonlinear strength criterion is developed for rocks by combining the Hoek–Brown (HB) criterion and the nonlinear… read more here.

DOI: 10.1007/s43452-021-00248-w
Abstract: Variations in the dynamic triaxial strength of hybrid basalt–polypropylene fibre-reinforced concrete (HBPRC) with strain rate and confining pressure were investigated, and a dynamic non-linear Mohr–Coulomb (M–C) strength criterion for HBPRC was established. The results showed… read more here.

DOI: 10.1016/j.jrmge.2016.11.010
Abstract: The present paper aims at giving some general ideas concerning the micromechanical approach of the strength of a porous material. It is shown that its determination theoretically amounts to solving a nonlinear boundary value problem… read more here.

DOI: 10.1016/j.mechmat.2020.103721
Abstract: Abstract A simple strength criterion J 2 = α + β σ 3 is investigated to describe the ultimate stress capacity of rocks. This criterion takes the intermediate principal stress σ 2 into consideration. The… read more here.

DOI: 10.1155/2021/6636968
Abstract: Samples of rock coupling joints were collected from the Jiangluling Tunnel of the G214 line in Qinghai province. Models with surface topographies similar to these joints were manually created. Freezing shear tests under different normal… read more here.
