In this paper, a simple model for the prediction of centrifuge cone penetration tip resistance in sand is presented. The proposed method, which relates the tip resistance to the pressure to expand a spherical cavity, refines and simplifies Greeuw’s original equations. The method assumed the failure mode of a spherical cavity expansion pressure given as a function of shear stiffness, angle of fr...

Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, effect connections between floors and walls is rarely discussed or explicitly modelled when simulating response such buildings. These are most commonly timber made planks beams, which supported on recesses can slide friction resistance reached. Using equivalent frame models, we capture effects bot...

Striated muscle is a linear motor whose properties have been defined in terms of uniaxial structures. The question addressed here is what contribution is made to the properties of this motor by extramyofilament cytoskeletal structures that are not aligned in parallel with the myofilaments. This question arose from observations that transverse loads increase muscle force production in diaphragm ...

Aortic wall stiffness, tear size and location and the presence of abdominal side branches arising from the false lumen (FL) are key properties potentially involved in FL enlargement in chronic aortic dissections (ADs). We hypothesize that temporal variations on FL flow patterns, as measured in a cross-section by phase-contrast magnetic resonance imaging (PC-MRI), could be used to infer integrat...

This work mainly aims to manufacture nanocomposite laminates at first. The prepreg AS-4 graphite/PolyEtherEtherKetone laminates were used to make a 16-layered APC-2 laminate of 2 mm thick via curing the modified diaphragm. The nanoparticles of Silica (SiO2) were uniformly spread on the specific interfaces totally about 1-3% by weight of a laminate by sol-gel method. Second, by the results of me...

Abstract. Thanks to their low friction, aerostatic pads are currently used in many high precision applications. However, due the air compressibility, bearings suffer from relatively stiffness and damping. Active passive compensation methods represent a valuable solution reduce these limitations. This paper presents novel prototype of diaphragm valve for passively compensated pads. The proposed ...

In this paper, using theory of sheets, the deflection of suspended diaphragm has been obtained under uniform and circular loading. This type of diaphragm, unlike other diaphragms, has a central support which is recommended to be used in MEMS applications. The relationship between diaphragm deflection and static analysis of this diaphragm enjoys a great significance in investigating and understa...
