Abstract This paper presents a novel, exact, semi-analytical solution for the quasi-static drained expansion of cylindrical cavity in soft soils with fabric anisotropy and structure. The assumed constitutive model is S-CLAY1S model, which Cam clay-type that considers evolves plastic strains, structure gradual degradation bonding (destructuration) due to straining. involves numerical integration...

Abstract A closed form analytical solution for both the quasi-static or dynamic strain hardening cylindrical cavity-expansion (CCE) problems requires plastic region to be incompressible. This is due fact that in cases a hydrostatic stress state must explicitly included function, making an intractable. Additionally, problem elastic compressible avoid logarithmic singularity at infinity. An alter...

Hysterosonography (SHG) is a new noninvasive technique that involves the slow infusion of sterile saline solution into the uterus during ultrasound imaging. Expansion of endometrial cavity by SHG allows optimal visualization and plays an important role in the evaluation of abnormalities related to the uterus. The most common indications for hysterosonography are: abnormal uterine bleeding both ...

In this paper, 3D particle focusing in a straight channel with asymmetrical expansion-contraction cavity arrays (ECCA channel) is achieved by exploiting the dean-flow-coupled elasto-inertial effects. First, the mechanism of particle focusing in both Newtonian and non-Newtonian fluids was introduced. Then particle focusing was demonstrated experimentally in this channel with Newtonian and non-Ne...

Lung ventilation in Siren lacertina was studied using X-ray video, measurements of body cavity pressure and electromyography of hypaxial muscles. S. lacertina utilizes a two-stroke buccal pump in which mixing of expired and inspired gas is minimized by partial expansion of the buccal cavity during exhalation and then full expansion after exhalation is complete. Mixing is further reduced by the ...

Aim: the aim of this study was to compare cusp deflection, infraction and fracture in teeth filled with three temporary filling materials. Materials & method: Forty five extracted human premolar teeth were chosen. After root canal therapy and mesio-occluso-distal cavity preparation, samples were randomly divided into three groups , each contained 15 teeth and filled with three temporary filling...

Abstract This paper presents an all-SiC fiber-optic Fabry-Perot (FP) pressure sensor based on the hydrophilic direct bonding technology for applications in harsh environment. The operating principle, fabrication, interface characteristics, and response test of proposed are discussed. FP cavity is formed by hermetically two-layer SiC wafers, including a thinned diaphragm wafer with etched cavity...

The lattice Boltzmann method (LBM) has recently become an alternative and promising computational fluid dynamics approach for simulating complex fluid flows. Despite its enormous success in many practical applications, the standard LBM is restricted to the lattice uniformity in the physical space. This is the main drawback of the standard LBM for flow problems with complex geometry. Several app...
