Formulation of Anisotropic Strength Criterion for Geotechnical Materials
Advances in Civil Engineering, 2020 A new nonlinear unified strength (NUS) criterion is obtained based on the spatially mobilized plane (SMP) criterion and Mises criterion. New criterion is a series of smooth curves between SMP curved triangle and Mises circle in the π plane and thereby ...

Dynamic strength criterion for rock-like materials
Yantu gongcheng xuebao, 2020 The strength of rock-like materials has obvious strain rate effect. Based on the characteristics of uniaxial dynamic strength, a simple strength criterion is proposed, which can uniformly predict the uniaxial strength from quasi-static to dynamic.

A true triaxial strength criterion for rocks by gene expression programming
Journal of Rock Mechanics and Geotechnical Engineering, 2023 Rock strength is a crucial factor to consider when designing and constructing underground projects. This study utilizes a gene expression programming (GEP) algorithm-based model to predict the true triaxial strength of rocks, taking into account the ...

Slope failure criterion for the strength reduction material point method
地质科技通报, 2022 It is necessary to select an instability criterion for the material point strength reduction method (SRMPM) to solve the slope safety factor (Fs), and there are some differences in the obtained Fs values with different instability criteria.
