A Unified Strength criterion for rock material
International Journal of Rock Mechanics and Mining Sciences, 2002Abstract A non-linear Unified Strength criterion for rock material is presented. It is the development of the Unified Strength Theory (in: M. Jono, T. Inoue (Eds.), Mechanical Behaviour of Materials-VI (ICM-6), Pergamon, Oxford, 1991, pp. 841–846) and the modification of the Hoek–Brown strength criterion (Underground Excavations in Rock, The ...

A criterion of strength for orthotropic materials
Fibre Science and Technology, 1975The criterion of strength for anisotropic media proposed by Gol'denblat and Kopnov2 is adopted in this paper. The invariants for the strength function having orthotropic symmetry are used to formulate a criterion of strength for orthotropic materials.

Strength of Materials, 2004
We propose a local criterion of brittle strength for structurally inhomogeneous materials based on the size effect of mechanical properties of materials under the conditions of stress concentration. It is assumed that the function of local strength of the material depends on the scaling factor equal to the ratio of the size of the zone of stress ...

RELATIVE STRENGTH AS A CRITERION FOR INVESTMENT SELECTION
The Journal of Finance, 1967AN EXTENSIVE BODY of literature has recently emanated from scholarly sources stating that successive stock market price changes are statistically independent (i.e., that the study of past price trends and patterns-known in the trade as technical analysis-is no more useful in predicting future price movements than throwing a dart at the list of stocks ...

A criterion for ascertaining the strength of composite materials
Computers & Structures, 1985Abstract This paper deals with the failure strength of composite materials in which the reinforcing filaments are parallel. According to this theory the strength of a unidirectional composite material is determined by a particular intermediate strain value and the orientation of the reinforcing filaments relative to the principal stresses.

Strength criterion for materials with different strengths in tension and compression
Strength of Materials, 1996It is shown that the fracture of materials which have different strengths in tension and compression and are highly sensitive to the sign of the spherical tensor can be described by using a criterion of the ductility of anisotropic bodies based on the invariance of the form of the limiting surface. Calculated values of breaking stress are compared with

Dynamic Strength Criterion for Concrete
Journal of Engineering Mechanics, 2004An integral dynamic strength criterion for concrete is proposed, which accounts for the short duration stress history in the range idealized as elastic. The concept of critical value of generalized stress impulse, proposed by Campbell for steel, was applied to concrete.

Fatigue Strength as a Design Criterion
SAE Technical Paper Series, 1970<div class="htmlview paragraph">The major factor determining the fatigue life of a welded structure under a given loading is the configuration of the weldments. The selection of various steel types and welding processes are considered to be secondary influences on the fatigue strength.

A New Strength Criterion for Concrete
ACI Structural Journal, 2002A new strength criterion defining the general ultimate stress of concrete is presented. A linear interpolation shape function in the deviatoric plane based on the Unified Twin-Shear Strength theory for all types of materials is developed. The criterion for concrete adopts the generalized linear interpolation functions in the deviatoric plane and the ...

Structurally heterogeneous material strength criterion
Strength of Materials, 1993We present the results of experimental and theoretical studies of the limit surface shape for a filled elastic polymer of heterogeneous structure. The construction of the strength criterion for the studied material is realized by a semiempirical method, analogous to the Mohr theory. The limit surface is approximated by two trihedral pyramids, narrowing
