The concept of representative crack elements has been successfully introduced to phase-field fracture in previous publications, where anisotropic elasticity [1], visco-elasticity [2], elasto-plasticity and surface friction [3] are considered at small deformations. This framework allows overcome unrealistic predictions for the kinematics, reported e.g. Strobl Seelig [4], Steinke Kaliske [5], kno...

Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand-fines mixtures under cyclic loading. results triaxial tests conducted Hostun sand with varying amounts (0–20%) types (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method, consolidated...

The creep associated with unloading surrounding rock during the excavation of deep tunnels seriously affects stability tunnel, and a high seepage pressure will aggravate strength attenuation structural deterioration rock. Based on background excavation-induced deeply buried granite tunnel pressure, in this paper we carry out triaxial test that considers effects both disturbance pressure. We als...

Tailings pond is a place for storing tailings or other industrial waste residues discharged from metal nonmetal mines after ore separation. The material will be into the stockpiling sorting and processing. hard to consolidate under natural conditions as result of high water content, resulting in certain safety risk pond. In this paper, tailing soil Huangshi City, Hubei Province studied triaxial...

An anisotropic damage model for vascular tissue is presented here. The widely used strain energy function in the quasi incompressible framework is exploited on its decoupled form to, additively, take into account the volumetric and the deviatoric contributions. Since a wellestablished neo-Hooke law is used to model the deviatoric part of the isotropic ground substance, this work focus on the co...

A finite element model was developed to simulate the vibratory stress relief after welding. Both resonant and nonresonant vibrations can relieve residual stresses in welded structures by creating plastic deformation around the weld area. For the non-resonant vibration, the stress reduction strongly depends on the vibration amplitude. For the resonant vibration, the vibration frequency is the ke...

Abstract The coexistence of air and water as a mixture in void spaces unsaturated soils, makes its mechanical behaviour relatively complex difficult to be addressed by classical saturated soil mechanics principles. In addition, many engineering problems encountered practical situations had some part deal with soils therefore the clear understanding various behavioural patterns is crucial. To da...

Recent evidence suggests that circulating leukocytes respond to physiological levels of fluid shear stress. This study was designed to examine the shear stress response of individual leukocytes adhering passively to a glass surface. Human leukocytes were exposed to a step fluid shear stress with amplitude between 0.2 and 4 dyn/cm(2) and duration between 1 and 20 min. The response of the cells w...
