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 ...

Multiaxial Strength Criterion Model of Concrete Based on Random Forest
Mathematics, 2023 The concrete strength criterion is the basis of strength analysis and evaluation under a complex stress state. In this paper, a large number of multiaxial strength tests were carried out, and many mathematical expressions of strength criteria were ...

A compressive strength criterion for anisotropic rock materials [PDF]
Canadian Geotechnical Journal, 1988 This paper proposes a general compressive strength criterion for anisotropic rock materials under multiaxial states of stress. The proposed criterion is a generalization of the Von Mises' criterion for yielding of ductile metals, which has also been used previously as a strength criterion for brittle fracture in the spirit of both being limits of ...

EMPIRICAL STRENGTH CRITERION OF COMPOSITE MATERIALS
Вестник Донского государственного технического университета, 2018 Empirical long-term strength criterion in terms of limit stress for constructive polymer materials considering ageing factor is found. The criterion corresponds to the type of Goldenblat - Kopnov.

Local and non-local normalised equivalent strain functionals for cyclic fatigue [PDF]
, 2004 The concept of Cyclic Normalised Equivalent Strain Functionals (CNESnFs) suitable for lowcyclic fatigue is developed in this paper. It reduces any fatigue strength and durability model to a unique form what facilitates the models comparison ...

Global subjective memorability and the strength-based mirror effect [PDF]
, 2009 Between-list manipulations of memory strength through repetition commonly generate a mirror effect, with more hits, and fewer false alarms for strengthened items. However, this pattern is rarely seen with within-list manipulations of strength.

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
