Distortion Strain Energy–Based Mohr-Coulomb Criterion for Concrete Failure

Journal of Materials in Civil Engineering, 2017
AbstractOn the basis of comprehensive analysis of experimental phenomenon and micro/mesomechanism, it is found that concrete failure is controlled by normal stress on failure plane and distortion s...

Evaluation of Aseismic Stability of Gangue Slope Based on Nonlinear Mohr-Coulomb Failure Criterion

Advanced Materials Research, 2011
It is extremely important to establish hazard maps showing earthquake-induced displacements, safety factors and probabilities of failure. The combination of pseudo-static method and displacement-based method is commonly used to evaluate the stability of gangue slope.

Mohr-Coulomb Failure Criterion Expressed in Terms of Stress Invariants

Journal of Applied Mechanics, 1998
A polynomial expression for the Mohr-Coulomb criterion for failure of brittle or frictional materials in terms of stress invariants is derived. The form of the polynomial expression corresponds to the pyramidal shape of the failure surface in principal stress space. The pressure-sensitive character of the failure of a Mohr-Coulomb material is indicated

Mechanics of Earth Fissures Using the Mohr-Coulomb Failure Criterion

Environmental and Engineering Geoscience, 2008
Earth fissures are approximately vertical cracks in the ground. They are caused by natural events such as earthquakes or by human activities such as groundwater level decline due to pumping. The latter has become a major worldwide issue in areas where groundwater is pumped for domestic, agricultural, and industrial use.

A Phenomenological Mohr—Coulomb Failure Criterion for Composite Laminates under Interlaminar Shear and Compression

Journal of Composite Materials, 2007
A new phenomenological delamination criterion has been proposed for considering the effects of through-thickness compression based on a modified Mohr—Coulomb friction mechanism. Published experimental results show that through-thickness compressions increase the interlaminar shear (ILS) strength nonlinearly, which requires a nonlinear friction ...

A study of the behaviour of brittle rocks subjected to confined stress based on the Mohr–Coulomb failure criterion

Geomechanics and Geoengineering, 2014
In this study the relationship between brittle rocks’ behaviour and uniaxial compression stress is obtained based on the Mohr-Coulomb failure criterion and the behavioural characteristics of brittle rocks under uniaxial compression stress are investigated.

A Modified Mohr-Coulomb Failure Criterion for Intact Granites Exposed to High Temperatures

2013
Rocks often experience high temperatures (several hundred degrees Celsius) due to underground operations, such as deep geological disposal of nuclear waste, geothermal heat extraction, CO2 geological storage and underground coal gasification as well as deep mining.

Experimental Study on Dynamic Strength Regional Characteristics of Undisturbed Loess Based on the Mohr-Coulomb Failure Criterion

Advanced Materials Research, 2013
Based on Mohr - Coulomb failure criterion, dynamic strength characteristic of undisturbed loess in Xining, Lanzhou, Xiji and Xian was studied through dynamic triaxial test. And the regional characteristics of void ratio, natural moisture content, plasticity index and dynamic shear strength with different vibration frequency and natural conditions were ...

Comparison of Hoek-Brown and Mohr-Coulomb failure criterion for deep open coal mine slope stability

Structural Engineering and Mechanics, 2016
In deep open pit mines, slope stability is very important. Particularly, increasing the depths increase the risks in mines having weak rock mass. Blasting operations in this type of open pits may have a negative impact on slope stability. Several or combination of methods can be used in order to enable better analysis in this type of deep open-pit ...

Mohr-Coulomb failure criterion from unidirectional mechanical testing of sand cores after thermal exposure

Journal of Materials Processing Technology, 2019
Abstract Sand core samples were subjected to thermal pre-conditioning profiles between 200 and 500 °C both in ambient air and under sealed conditions. These were customised similar to an industrial cast aluminium cylinder head. The samples were investigated via unconfined compression, splitting tensile, shear, and bending tests.
