Abstract:

To solve the classical problem that the Mohr–Coulomb yield criterion overestimates the tensile properties of geotechnical materials, a modified Mohr–Coulomb yield criterion that includes both maximum tensile stress theory and smooth processing was established herein. The modified Mohr–Coulomb constitutive model is developed using the user-defined material subroutine (UMAT) available in finite element software ABAQUS, and the modified Mohr–Coulomb yield criterion is applied to construct a numerical simulation of a shaking table model test. Compared with the measured data from the shaking table

Abstract:

In this paper, taking elastic and plastic characteristics of rock into account, the authors have studied the relationship between different constitutive models. By transforming material parameters merely, on the basis of Equivalent Mohr-Coulomb Yield Criterion, the researchers achieved the application of these relationship in the computer program-Ansys5.7. They also have discussed the magnitude relationship between the transformed parameters and the original ones. By analyzing the cases of rock slope with obvious sliding surface, the researchers proved that it is liable to replace Mohr-Coulomb

Cambridge model gets the extensive application, which has advantages of rigorous theoretical derivation and model parameters which can entirely be obtained by triaxial tests, while it has deficiencies of the narrow applicative scope and describing the dilatancy hardly.

On account of the critical state of dilatancy defined comprehensively, this paper based on the description of dilatancy combines the advantage of Cambri

The results of slope stability analysis are not unique. Different factors of safety are obtained investigating the same slope. The differences result from different constitutive models including different failure surfaces. In this contribution, different strength reduction techniques for two different constitutive models (linear elastic - perfectly plastic model using a Mohr-Coulomb failure criterion and barodesy) have been investigated on slope stability calculations for two different slope inclinations.

The constitutive model is the crucial part for the finite element analyses.

Abstract:

The compressibility of mining backfill governs its resistance to the closure of surrounding rock mass, which should be well reflected in numerical modeling. In most numerical simulations of backfill, the Mohr–Coulomb elasto-plastic model is used, but is constantly criticized for its poor representativeness to the mechanical response of geomaterials. Finding an appropriate constitutive model to better represent the compressibility of mining backfill is critical and necessary. In this paper, Mohr–Coulomb elasto-plastic model, double-yield model, and Soft Soil model are briefly recalled. Their ap

This paper presents a new constitutive model for describing the strain-hardening and strain-softening behaviors of clayey rock. As the conventional Mohr-Coulomb (CMC) criterion has its limitation in the tensile shear region, a modified Mohr-Coulomb (MMC) criterion is proposed for clayey rock by considering the maximal tensile stress criterion. Based on the results of triaxial tests, a coupled elastoplastic damage (EPD) model, in which the elastic and plastic damage laws are introduced to describe the nonlinear hardening and softening behaviors, respectively, is developed so as to fully describ

Abstract:

For concrete face rockfill dams, the behaviour of the concrete slab which provides the watertightness of the dam is a major concern. The deformation of the dam embankment during construction and operation leads to concrete slab deformation. This deformation should be compatible with the structural integrity of the concrete slab. This paper presents the numerical analysis of El-Agrem concrete face rockfill dam during reservoir filling using the finite element code Plaxis 2D-2010. Two models are used in this study, the Mohr Coulomb model and the Hardening Soil model to emphasize the impact of co

Stabilitas lereng merupakan salah satu faktor penting yang harus diperhatikan dalam merancang suatu lereng batuan. Aktivitas penggalian dalam massa batuan dapat mengakibatkan terjadinya kelongsoran atau keseimbangan lereng terganggu. Analisis stabilitas lereng batuan dapat dipengaruhi oleh tiga faktor seperti kekuatan massa batuan, faktor kerusakan akibat peledakan dan geometri lereng. Pada penelitian ini akan dilakukan perbandingan analisis lereng batuan menggunakan model material Hoek-Brown (HB) dan Mohr-Coulomb (MC) berdasarkan persamaan Hoek-Brown Tahun 2002.

Abstract:

The Mohr-Coulomb (M-C) failure criterion has been a popular choice for geotechnical analysis because of its simplicity and ease of use. The fact that the M-C criterion disregards the intermediate principal stress’s impact is a significant drawback. As a result, the M-C criterion is only applied to materials under biaxial stress. This paper presents a three-dimensional version of the M-C criterion. The proposed criterion, called the Generalized Mohr-Coulomb (GMC) criterion, considers the intermediate principal stress’s effect, in addition to inheriting the original M-C criterion’s benefits. We

Abstract:

The paper analyzes the physical models used in the study of the stressed state of geological rocks. Common physics models include: 1) soil and foam; 2) pseudo-tensor; 3) geological; 4) Schwer-Murray; 5) continuous surface of the cap; 6) Mohr-Coulomb; 6) connected stone. A graphical representation of the description of the soil and foam model is given. At the initial stages of loading with small deformations, the model behaves linearly elastically. When the level of deformations increases, it turns into a non-linear model. The graphical presentation of the pseudo-tensor model reflects two modes

This article deals with the behavior of isolated piles subjected to two models used in geotechnics (Hardening Soil and Mohr Coulomb) under cyclic lateral loading and their head deformations compared to monotonic loading in sandy soil. The behavior of the cable-stayed bridge piers was predicted using PLAXIS 2D software, based on the results of in situ and laboratory geotechnical studies carried out by the control office for Building and Public Works (BCBTP). Numerical simulation is an alternative to the high cost of large-scale in situ and laboratory studies for describing the behavior of deep

Abstract:

Cohesion is defined as the shear strength of material when compressive stress is zero. This article presents a new method for the experimental determination of cohesion at pre-set angles of shear deformation. Specially designed moulds are created to force deformation (close to τ-axis) at fixed pre-set values of angle with respect to normal stress σ. Testing is performed on series of concrete blocks of different strengths. From the compressive side, cohesion is determined from the extrapolation of the linear Mohr–Coulomb (MC) model, as the intercept on the shear stress axis. From the tensile st

A generalized numerical model which allows for a variety of non-linear rheologies is developed for the seasonal simulation of sea-ice circulation and thickness. The model is used to investigate the effects (such as the role of shear stress and the existence of a flow rule) of different rheologies on the ice-drift pattern and build-up in the Arctic Basin. Differences in local drift seem to be closely related to the amount of allowable shear stress. Similarities are found between the elliptical and square cases and between the Mohr-Coulomb and cavitating fluid cases. Comparisons between observed
