Strength criterion for frozen saline sand considering effects of loading rates
Yantu gongcheng xuebao, 2019 The external conditions such as confining pressures and loading rates have significant influences on the strength of frozen saline soil. A series of conventional triaxial compression tests under different loading rates are carried out for Delingha frozen

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 Criterion for Comparing Strength of Preference with an Application to Bargaining [PDF]
Operations Research, 1992 A criterion called “improving faster than” is proposed and characterized to compare the strength or preference of value functions. The result can be applied in decision models where no risk is involved or, at least, explicitly modeled. A bargaining theory example illustrates the criterion.

Fracture Characteristics and Anisotropic Strength Criterion of Bedded Sandstone
Frontiers in Earth Science, 2022 Bedded sandstone is classified as sedimentary rock, which is a typical bedded rock with obvious layered structure characteristics. Bedded rocks formed different bedding orientations in the long and complicated geological tectonic evolution and thus have ...

Evaluation of strength of spherical contact pairs of aviation structures
Aviation, 2010 The strength criterion is used to evaluate the spherical contact pairs of the aviation structures. The strength criterion helps evaluate triaxial tension in the contact pair. Calculations reveal the acceptability of the suggested criterion. Santrauka
