Abstract:

In this work, calculations of the hydrostatic strength of a spheroplastic are carried out using the previously described empirical formula. The calculations were based on the physical and mechanical characteristics of the polymer binder and hollow glass microspheres. Measurements of the physical and mechanical characteristics of the polymer binder, hollow glass microspheres and spheroplastics were performed with standard methods: dynamic mechanical analysis (DMA), gas and hydrostatic pycnometers. The results of tensometric tests of Poisson’s ratios of binders were also used. The hydrostatic st

Abstract:

This paper presents first results of noncohesive soil direct shear tests with hydrostatic pressure. To reach this aim, it was chosen the Baltic Sea Klaipėda sand, due to granulometry composition and particles shape. According to this, investigated Baltic Sea sand can be called Lithuanian standard sand for scientific testing. Analysis of results revealed, that when it is increased hydrostatic pressure, the shearing strength is also increasing. Comparing air dry sand results with fully saturated sand and affected with 100 kPa of hydrostatic pressure, the angle of internal friction increased fo

Abstract:

Magnesium wrought alloys are of special interest for structural components owing to their improved microstructures and mechanical properties by comparison with Mg cast parts. However, the market of Mg wrought alloys is still relatively small and one of the most important limitations for their application in areas such as aviation and spaceflight is that their strength is still not high enough to be widely used. Currently, more and more attention are paid to hydrostatic extrusion of Mg alloys because the extruded Mg alloys which exhibit extremely fine grains and high strength can be easily obta

Abstract:

This research paper represents interpretation of engineering geological and geotechnical conditions by using a direct shear device with a possibility to apply hydrostatic pressure during the experimental testing. In the authors’ opinion, the evaluation of in-situ hydrostatic pressure and reconstruction of it in the laboratory tests is a very important step in the determination of the engineering geological and geotechnical properties of the sand strength and its behaviour. To understand the influence of hydrostatic pressure on shearing strength results, there were performed direct shear tests

Abstract:

Registration of acoustic emission in the process of spheroplastics destruction in a high-pressure hydrostatic chamber is realized. Hardware design does not require specialized equipment and is based on available components. Time synchronization on pressure and acoustic emission graphs ensures pressure fixation of pressures at which the formation of cracks in the spheroplastic sample begins. It is shown that accumulation of destructions begins with pressure, smaller, than pressure fixed as short-term hydrostatic durability.

Thus, this method does not allow for the assessment of an impact of hydrostatic pressure and stress path on the value of cohesion, friction angle and global uniaxial compression of rock mass.

Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.

Abstract:

Based on a systematic literature review, no design guidelines addressing practical issues related to steel circular hollow section (CHS) members under hydrostatic pressure have been documented thus far, except for the design recommendations proposed by the European standard EN 1993-1-6 concerning the strength and stability of shell structures. Considering that the existing codes are often outdated and subject to improvement, there is a growing demand for modern solutions that can accurately replicate the stability loss response of equipment subject to external pressure.

Abstract:

Polymers offer a lightweight, low cost option for solar hot water system components. Key to the success of polymer heat exchanger components will be the long term mechanical performance of the polymer. This is particularly true for heat exchangers in which one of the fluids is pressurized hot water. For domestic hot water systems, polymer components must not fail after many years at a constant pressure (stress levels selected to correspond to 0.55 MPa in a tube) when immersed in 82°C potable water. In this paper, the long term performance of two potential heat exchanger materials, polybutylene

Abstract:

Recently, submersible pressure hulls with fiber-reinforced multilayer constructions have been developed as substitutes for classical metallic ring-stiffened pressure hulls. The strength and stability is its top priority. In this paper, the optimum design of elliptical composite deep-submerged pressure hull under hydrostatic pressure is investigated based on the finite element analysis to minimize the buoyancy factor of the submersible pressure hull according to the design requirements. Minimize the buoyancy factor of a submarine pressure hull under hydrostatic pressure is proposed as an object

Abstract:

Hydrostatic extrusion can be viewed as one of the methods of Severe Plastic Deformation, SPD, for the fabrication of ultra-fine grained alloys which causes a significant increase in the mechanical properties such as tensile strength and hardness. In the present study the microstructure of 6082 aluminium alloy after hydrostatic extrusion was investigated. Hydroextrusion was performed in three steps with accumulated true strains of 1.34, 2.73 and 3.74 respectively. Microstructural observations were carried out using SEM, TEM and light microscopy.

This paper presents the design optimization of filament winding composite cylindrical shell under hydrostatic pressure to maximize the critical buckling pressure. To this end, an optimization framework has been developed by employing numerical solution integrated with genetic algorithm. The design variables are fiber orientation and the corresponding number of layers. The framework is used to find the optimal design of filament winding composite cylindrical shell subjected to hydrostatic pressure. Three types of winding pattern are investigated, and the maximum critical buckling loads are incr

Abstract:

Experiments show that the failure of ductile materials can be characterized by a rate-independent parameter, relative spacing d defined as the ratio of the distance between two voids and the radius of voids. In this study, this experimental phenomenon is analyzed via numerical simulations using 3-D finite element model. Considering that hydrostatic stress is a dominant factor in the evolution of microvoid nucleation, growth and coalescence in ductile materials, numerical simulations are performed to obtain the relationship between relative spacing d and hydrostatic stress in the ligament betwe

Abstract:

The mechanical properties of titanium Grade 2 subjected to the hydrostatic extrusion technique (HE) were investigated. The hydrostatic extrusion technique is a method which refines the titanium grains to a nano-metric size. Compared with coarse grained titanium (CG-Ti), nanocrystalline titanium (NC-Ti) is characterized by a much higher yield stress, tensile strength and microhardness. The yield stress of NC-Ti determined in tensile tests is higher than that measured in compression test. The Young modulus of NC-Ti is slightly lower than that of CG-Ti.
