Study on strength criterion for frozen soil
Cold Regions Science and Technology, 2019Abstract 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.

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.

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 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 ...

An empirical strength criterion for heterogeneous tuff
Engineering Geology, 1992Abstract 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, 2019Abstract 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

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 statistical strength criterion for brittle materials
Strength of Materials, 2011Based 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 ...

Choice of strength criterion for rigid thermosets
Polymer Mechanics, 1969On the basis of experimental data obtained by testing rigid thermosetting plastics under plane stress conditions the authors analyze the applicability to these plastics of the first and second classical theories of strength as well as the theories of Mohr, Yagn, Balandin, and Mirolyubov.
