A criterion of strength for orthotropic materials

Fibre Science and Technology, 1975
The 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.

Study on strength criterion for frozen soil

Cold Regions Science and Technology, 2019
Abstract It is established that the strength of frozen soil exhibits apparent nonlinearity in the p–q plane. As the mean stress p increases, in certain experimental conditions, the strength of frozen soil increases rapidly and then reduces gradually; however, in certain other conditions, the strength increases gradually and then reduces rapidly.

A New Strength Criterion for Concrete

ACI Structural Journal, 2002
A 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 ...

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.

RELATIVE STRENGTH AS A CRITERION FOR INVESTMENT SELECTION

The Journal of Finance, 1967
AN 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 ...

Sufficient Discrete—Integral Criterion of Rupture Strength

Journal of Applied Mechanics and Technical Physics, 2001
The behavior of the atomic structure in the vicinity of the crack tip is modeled. The loss of stability and postcritical deformation of a triatomic cell in a close–packed atomic layer in tension are studied. For macrocracks in single crystals, the concept of the generalized Burgers vector is introduced. A sufficient discrete—integral strength criterion

A statistical strength criterion for brittle materials

Strength of Materials, 2011
Based on a probabilistic model of brittle microfracture (microdamage) leading to macrofracture of materials, we propose a statistical interpretation of strength criteria, which relate start of macrofracture (manifested by macrocrack formation in tension or internal structure stability loss in compression) with attainment of a certain (critical) value ...

An empirical strength criterion for heterogeneous tuff

Engineering Geology, 1992
Abstract An empirical failure criterion is formulated by expressing the second invariant of stress deviation at failure as a function of the first invariant of stress, key parameter, and volume. Strength data from Apache Leap tuff specimens are analyzed as a demonstration example.

A strength criterion for frozen moraine soils

Cold Regions Science and Technology, 2019
Abstract The strength behavior of frozen soils has been extensively investigated in frozen soils mechanics for many years. In order to study the strength properties of frozen moraine soils, a series of cryogenic tri-axial compression tests are carried out under confining pressures ranging from 0.5 MPa to 16 MPa at the temperatures of −0.5 °C, −2.0 °C

An Improved Multiaxial Creep-Rupture Strength Criterion

Journal of Pressure Vessel Technology, 1985
An improved strength model is developed for predicting creep rupture under multiaxial stress states. The new model incorporates three independent stress parameters and distinguishes between life under tensile versus compressive stress states. Assessments of the new model based on experimental biaxial creep-rupture data for type 304 stainless steel ...
