The bearing capacity of strip footings on unsaturated soils is studied using slip line theory. The suction profiles considered are non-uniform with depth and correspond to vertical flow of water by infiltration or evaporation. The slip line theory assumes a plastic equilibrium state of a Mohr-Coulomb soil in which suction influences are included using the effective stress concept. This paper sh...

We present the first rigorous examples of non-singular Hubbard models which exhibit ferromagnetism at zero temperature. The models are defined in arbitrary dimensions, and are characterized by finite-ranged hoppings, dispersive bands, and finite on-site Coulomb interaction U . The picture, which goes back to Heisenberg, that sufficiently large Coulomb interaction can revert Pauli paramagnetism ...

High-amplitude seismic waves from the Mw 7.0 Kumamoto earthquake of April 16, 2016, triggered another large earthquake 80 km to the NE roughly 30 s later. The source was located at shallow depths beneath the Yufuin geothermal field, Oita Prefecture, Japan, and the event magnitude was approximately 5.9. To date, this is one of the clearest known examples of a remotely triggered large earthquake....

The shallow shelf approximation is a better “sliding law” for ice sheet modeling than those sliding laws in which basal velocity is a function of driving stress. The shallow shelf approximation as formulated by Schoof [2006a] is well-suited to this use. Our new thermomechanically coupled sliding scheme is based on a plasticity assumption about the strength of the saturated till underlying the i...

Because the interaction is well-known, Coulomb excitation is one of the best tools for the investigation of nuclear properties. In the last 3 decades new reaction theories for Coulomb excitation have been developed such as: (a) relativistic Coulomb excitation, (b) Coulomb excitation at intermediate energies, and (c) multistep coupling in the continuum. These developments are timely with the adv...

Coulomb excitation has proven itself as an important tool for studying the structure of both stable and exotic nuclei.[1– 4] The phenomenon has been well-studied in a nonrelativistic context[5] and studied perturbatively in a relativistic one[6] by Alder and Winther. More recent experimental studies have considered multiple Coulomb excitation at relativistic energies.[2–4] Many calculations of ...

The islands of Sumatra and Sinabung are located southwest the Sundaland Continent which is a convergence route between Indian-Australian Plate that infiltrates to west Eurasian/Sundaland Plate. increase in activity Mount was preceded by large earthquakes south while eruption produced pyroclastics. purpose this study find out analysis coulomb stress from Island earthquake pyroclastic flow as dat...

Abstract In the present work, numerical models are developed for shearing and cutting process of advanced high strength steel-blanks which can predict edge morphology in shear effected zone. A damage model, based on modified Mohr-Coulomb fracture surface, is calibrated. To increase predictability models, surface fine-tuned areas corresponding to stress-state cutting, a methodology called Local ...

The MTS815 mechanics system is used to perform triaxial compression tests water-saturated sandstones different confining pressures and pore water pressures. results show that the peak deviation stress its corresponding axial strain, residual stress, initial dilation deformation modulus sandstone are related pressure p...

Here a short synthesis is presented of the work, developed in the last two years by the Brescia Collaboration, on the phenomenology of antinucleon-nucleon and antinucleon-nucleus annihilation at small momenta (below 300 MeV/c in the laboratory), with special stress on the role of general principles. Our work[1] in the last two years was mainly devoted to the study of the strong shadowing charac...
