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: 10.3390/math13233890
Abstract: To address the limitation of using experimental parameters in the macroscopic strength criterion, a micromechanical strength criterion for root-reinforced soil is developed. In this model, a micromechanical model for a three-phase composite (“root—cemented soil matrix—frictional… read more here.
