[1] We calculated static stress changes from the devastating M = 7.6 earthquake that shook Kashmir on 8 October, 2005. We mapped Coulomb stress change on target fault planes oriented by assuming a regional compressional stress regime with greatest principal stress directed orthogonally to the mainshock strike. We tested calculation sensitivity by varying assumed stress orientations, target-faul...

a new dynamic friction model for modeling of elliptical vibration assisted turning (evat) was developed in this research. the periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. in modeling of machining processes (including the evat process), static coulomb friction model was employed by most of the researchers. because of the peri...

Abstract Wellbore instability problems cause nonproductive time, especially during drilling operations in the shale formations. These include stuck pipe, caving, lost circulation, and tight hole, requiring more time to treat therefore additional costs. The extensive hole collapse problem is considered one of main challenges experienced when Zubair formation. In turn, it caused by increasing wel...

On 5 September 2022, an Ms6.8 magnitude earthquake occurred in Luding County, Sichuan Province, China. Based on Sentinel-1 SAR images, this paper uses the D-InSAR approach to obtain displacement field of earthquake, invert coseismic sliding distribution, and then calculate static coulomb stress changes deformation aftershock distribution surrounding faults. Further, seismic structure is analyze...

in this paper, using monte carlo fortran code, we have obtained the binding energies for three different systems of diquark–antidiquark in distances from 0.01 to 15 nm. in [0.1 - 15] nm interval, we made use of coulomb potential because in this interval, strong interaction is negligible. we have compared the binding energies of the systems with one another. the results of these comparisons were...

We discuss the elementary physics of the final state Coulomb interactions in HanburyBrown Twiss interferometry, showing – with explicit comparison to E877 data for π+π− and π±p – that the Coulomb corrections in the pair correlation function can be well understood in terms of simple classical physics. We connect the classical picture with descriptions in terms of Coulomb wave functions, and inve...

A new hyper-elastic formulation is proposed for improving the convergence of Mohr–Coulomb-like constitutive models at small stresses, when problems come from vicinity to apex yield surface and elastic predictor can lay in a region which not defined. The avoids stress states with tensile mean pressures provides shear bulk stiffnesses increasing square root stress, as typically occurs granular so...

Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...
