We present a two-dimensional analytical solution for the static stress field around rough interlocked interface under background stresses and its applications to faulting. The is derived using perturbation theory defined topography stresses. failure-ratio, which scales likelihood failure of bulk material interface, calculated adopting Coulomb criterion. compare model predictions with results ex...
Long-term stress accumulation influenced by coseismic changes and postseismic viscoelastic relaxation is considered critical to triggering giant earthquakes. Nevertheless, how the increase interrupted aftershocks it influences megaseismic cycle remain enigmatic. In this study, based on Mohr–Coulomb failure criterion at nucleated segments of 2008 great Sichuan earthquake, variation associated wi...
This paper presents a new formulation of a well known double hardening model often referred to as the Hardening Soil model. As an alternative to the existing Hardening Soil model’s Mohr-Coulomb failure surface, the new formulation allows for the incorporation of smooth failure surfaces, such as the failure surface proposed by Matsuoka & Nakai or that proposed by Lade & Duncan. Although the inco...
Samples of 10 and 14 Ctenocephalides felis felis fleas were collected on dogs from Pedreira and Mogi das Cruzes municipalities, respectively, in the State of São Paulo, Brazil, for detection of Rickettsia spp. Individual fleas were submitted to Polymerase Chain Reaction targeting the 17-kDa and the 190-kDa (OmpA) genes of Rickettsiae. This later gene is specific for spotted fever group. Nine fl...

composite pressure vessel cng made of epoxy – carbon material with nonmetal liner is 60% lighter than aluminum vessel under the same conditions. one of the important parameters in the pressure vessels design is their resistance against impact and prevention of explosion. in this paper, the effects of low velocity impact on composite pressure vessel are investigated using fe analysis. the vessel...
Abstract The triaxial mechanical properties of hybrid basalt–polypropylene fibre-reinforced concrete (HBPRC) were investigated in detail. different effects micro-basalt fibre (BF) and micro-polypropylene (PF) on the revealed. strength criterion for HBPRC was established. results showed that hydrostatic behaviour, volumetric strain, peak deviatoric stress, elastic modulus, Poisson’s ratio are af...
In the current paper the results of a numerical simulation that were verified by a well instrumented experimental procedure for studying the arching effect over a trapdoor in sand is presented. To simulate this phenomenon with continuum mechanics, the experimental procedure is modeled in ABAQUS code using stress dependent hardening in elastic state and plastic strain dependent frictional harden...
A finite element program based on elastic –plastic model of Mohr-Coulomb criterion was used to evaluate the bearing capacity coefficients of soil under shallow strip flexible footing . The results were compared with others’ analytical results and it was found that the present study could offer quite consistent and rather precise values for the bearing capacity coefficients . 

The effect ...
