Molekulare Ursachen des Mohr-Tranebjaerg-Syndromes
The molecular basis of the Mohr-Tranebjaerg syndrome: A structural and functional analysis of the proteins DDP1 and Tim13 Mohr-Tranebjaerg syndrome is a mitochondrial disorder caused by a defects in the biogenesis of the human TIM23 translocase Tim8 and Tim13 of yeast belong to a family of …

Application of new observational method on deep excavation retaining wall design in London Clay
… excavation cases are back-analysed by the Mohr-Coulomb model using FEMs from Pseudo-FEM to 2D and 3D FEMs. The Crossrail Tottenham Court Road Station, Western Ticket Hall deep box excavation is also back-analysed by the BRICK model using the 3D FEM, representing the advanced soil model. The …

An investigation into the failure of neat cement cylinders under independently controlled confining pressure, pore pressure, and axial force
… specimen occurred. The results indicated that Mohr's Theory by no means begins to explain the complex nature of the failure of the material. An envelope of failure was defined by the circles of stress; however, the failure angles indicated by Mohr's graphical solution did not compare well with …

Strength of non-persistent rock joints
… and tension failure between the joint rows). The Mohr-Coulomb shear criterion is suitable for predicting failure along the joints; but failure by stepping needs another approach, which takes into account the failure in tension. The Mohr-Coulomb criterion in conjunction with the proposed expression …

Two-Dimensional Analysis of Water-Filled Geomembrane Tubes Used as Temporary Flood-Fighting Devices
… built-in soil models are used: elastic and Mohr-Coulomb. The Mohr-Coulomb model is used in all the cases except the preliminary analyses, in which the elastic soil model is used. The Mohr-Coulomb soil model is able to model the soil's nonlinear stress-strain and path-dependent deformation …

Shear and normal stresses in uniaxial compaction.
… The data obtained was presented in the form of Mohr circles, stress pathways (shear-mean compaction stress planes) and a three dimensional representation in mean compaction stress, shear stress and volume change. The yield loci evaluated from Mohr circles and shear-mean compaction stress …

Lower-bound shakedown analysis of pavements by using the interior point method
… As yield conditions, the rounded Mohr-Coulomb, Tresca and von Mises yield criteria are used, assuming associated flow rules. The proposed numerical method is based on finite elements and the inherent optimization problem to determine the shakedown factors is solved with the …

A finite element analysis of the pullout capacity of suction caissons in clay
… finite element program Plaxis is used and a Mohr-Coulomb model is assumed for the soil. Comparisons are presented between the results of this study, the theoretical Mohr-Coulomb model predictions and other finite element analysis found in the research for undrained and drained loading.

Finite deformation of particulate geomaterials: frictional and anisotropic Critical State elasto-plasticity
… geometrically non-linear behaviour. The Mohr-Coulomb and modified Cam-clay constitutive models have both been examined and extended to provide greater realism. Findings from this thesis will interest engineers working in numerical methods in solid mechanics, along with those investigating …

Time integration schemes for piecewise linear plasticity
… isotropic material behavior. Both the Tresca and Mohr-Coulomb yield surfaces with perfectly plastic and linear hardening rules are considered in detail. The algorithm has the advantage of being fully linked to the governing principles and avoids the inherent problems associated with corners on the …

A study of x-ray substructure in rich clusters of galaxies
… used are: the 'center shift' method developed by Mohr et al., the 'moment' method developed by Buote & Tsai and a wavelet analysis developed by Starck et al. Models were then created to check the significance of our findings. The conclusions reached were that substructure and cooling flows are …

Application of lower bound limit analysis with second-order cone programming for plane strain and axisymmetric geomechanics problems
… is established. For the axisymmetric case, the Mohr-Coulomb yield criterion is formulated as a set of second-order cones, which gives rise to a second-order programming problem, which provides computationally more efficient method for numerical lower bound limit analyses of an axisymmetric …

Stress-density relationships for an agricultural soil
… used to evaluate the soil parameters under the Mohr-Coulomb failure criteria. Furthermore, the influence of the initial soil density on the soil behavior was evaluated and subsequently compared to the results of a similar study conducted under a different initial density.
