Investigation of the load transfer of concrete plugs to tubular steel piles subjected to tension and compression and cyclic loading has been conducted at Monash University over the past 3 years. The work presented in this paper reports on the results of the combination of pull-out, push-out, and cyclic loading tests carried out on 15 steel tube specimens filled partially with reinforced concrete with variable lengths of embedment. The pull-out force was applied through steel reinforcing bars embedded in the concrete plug, and push-out forces were applied through a thick top circular plate on t

AbstractIn this paper, an efficient method is proposed to derive cyclic p-y curves from either push-over or shaking table test results. The Fourier series function, satisfying the boundary conditions of a pile, is used to represent deflection behavior of the pile-soil system at each instant of time during loading interval. In order to obtain soil reaction along the pile shaft, convergence of the series after differentiation is guaranteed by applying the Cesaro sum technique. Results of four push-over tests and two other shaking table test results, conducted at the National Center for Research

Abstract Three melts of ferrite-pearlitic nodular cast iron with different charge composition were used for fatigue tests. Wöhler fatigue curves and fatigue strength were obtained, and microstructure and fracture surfaces were investigated. The aim of the paper is to determine the influence of charge composition on microstructure, mechanical and fatigue properties of synthetic nodular cast irons and their micromechanisms of failure. Fatigue tests were realised at low frequency sinusoidal cyclic push-pull loading (stress ratio R = −1) at ambient temperature (T = 20 ±5°C). They were carried out

Push-out tests were conducted to study the performance of shear studs in composite beams with profiled sheeting. All stud specimens were through-deck welded on steel beams. Three variables, i.e. the presence of profiled sheeting, the direction of the steel sheeting and the loading patterns were studied. Comparison between test results and predictions according to design specifications were also proposed. The research shows that, direction of the profiled steel sheeting has little influence on the ultimate load with shank shearing failure; shear failure of concrete rib decreases the shear stren

Multiaxial fatigue tests consisting of push-pull loading and cyclic inner pressure were carried out using hollow cylinder specimens of type 430 stainless and type 316 stainless steels at room temperature. 7 types of cyclic loading paths were employed by combining axial and hoop stresses: a Pull, an Inner-pressure, a Push-pull, an Equi-biaxial, a Square-shape, a LT-shape and a LC-shape. Fatigue lives vary depending on the loading path when those were evaluated by the maximum Mises’ equivalent stress on inner surface of the specimen. The fatigue lives of both the steels showed a similar tendency

Abstract The low-cycle and high-cycle fatigue behavior of the Mg-base wrought alloy AZ31 is investigated in the temperature range 20– 300 °C using total-strain-controlled push – pull tests. It is shown that the mechanical properties of the material are substantially influenced by the direction dependent formation of deformation twins and resulting deformation asymmetry. As a consequence tensile mean stresses develop during total-strain-controlled fatigue tests without mean strain.

Industrial steel storage racks are pre-engineered lightweight structures commonly used to store goods from supermarkets to big warehouses. These systems are framed structures, usually made of cold-formed steel profiles and characterised by non-standard details. Their performance is quite complex and the prediction of their global response is more difficult than for the traditional steel frames. This difficulty is due to the racks’ main features: the use of cold-formed thin-walled steel sections which are sensitive to different buckling modes, the presence of regular perforation patterns on the

Since the early 1990s, at least forty-five initiatives have been mounted to improve the environmental and social performance of the mining industry. Many changes in the formal legal and regulatory systems have also been introduced. However, no systematic approach has been adopted to test whether this effort is making a difference. Without such monitoring of success, the tension between companies, communities, and governments regarding the role of mining in society will continue.

The life-cycle model yields a number of important empirical predictions about consumption and saving behavior. First, the growth rate of consumption depends on the difference between the expected real interest rate and the rate of time preference and varies with the elasticity of intertemporal substitution. Second, individuals seek to smooth the marginal utility of consumption over time. Third, young consumers should be accumulating resources for retirement, and hence have an adequate level of wealth at retirement. Finally, the elderly should be decumulating resources.

Abstract The effect of applied potential and chloride concentration on localized corrosion and stress corrosion cracking (SCC) of austenitic stainless steels (SSs) and Ni-base alloys was studied. The repassivation potential, Erp, for deep pits was the same as that for crevice corrosion. Laboratory tests over a two-year period and field experience have shown that the Erp is a conservative parameter to predict the occurrence of both these failure modes. For type 316L SS, the U-bend SCC test was found to be more conservative than the slow strain rates tests under controlled potential conditions f

Abstract A number of bare and precoated steels are used in the automotive industry. The selection of these products as to corrosion resistance should depend upon the vehicle environments in which they are exposed. Although a lot of fragmented knowledge is present in the area of automotive corrosion control there is a gap between usual performance testing (e.g. salt spray tests, etc.) and the final corrosion behaviour to be expected in the vehicle. To fill up this gap a research program was carried out to achieve a new standard corrosion test from actual measurements of the corrosive conditions

Abstract An experimental program was carried out to develop a procedure which will reliably assess the stress-corrosion cracking susceptibility of a given line pipe steel. The commonly used test methods such as slow strain rate and precracked specimen testing have been found to be deficient for this purpose because they are severe test methods which do not approximate service conditions or discriminate between similar steels. On the other hand, constant load or constant displacement tests are more discriminatory but are time consuming and expensive. Previous studies performed at Battelle and t

Abstract Comparisons of the corrosion resistance performance of a novel polyaniline based double strand conductive polymer coating versus a chromate conversion coating on two aluminum alloys were made. Potentiodynamic scans, electrochemical impedance spectroscopy (EIS) in 0.5N NaCl solutions and ASTM B-117 salt spray tests were performed on coated samples of AA7075-T6 and AA2024-T3 aluminum alloys. Results show the conductive polymer film offers, at the least, an equivalent protection performance as the chromate coating with a two order of magnitude reduction in corrosion current densities in

Abstract Ac impedance and dc polarization tests of 304 stainless steels coated by cathodic arc plasma deposition (CAPD) titanium nitride and zirconium nitride were conducted in aqueous chloride solution. Cyclic polarization data suggested passive films were formed over the nitride coatings which are most likely hydrated titanium oxide and zirconium oxides. ESCA analysis of fresh samples and samples exposed during impedance tests indicated a layer rich in oxygen over the ZrN coating after exposure but not over TiN coating. Chemical shifts in the Zr 3d5/2 core electrons indicate transformation f

Abstract Environment-assisted cracking (EAC) of aluminum alloys in corrosive atmospheres is a significant maintenance and safety issue for aerospace and naval structures. EAC is influenced by the interaction of stress, environment, and alloy microstructure. Atmospheric environmental conditions and corrosion kinetics are dynamic due to diurnal cycles and changing operating conditions, where temperature, relative humidity, and surface contaminants interact to control thin film electrolyte properties. In the case of EAC and other localized corrosion processes, such as crevice corrosion, separatio

The ATDs required in the aviation regulations were initially developed for the automotive crash environment, which does not include a vertical testing component. One of the two dynamic tests is a vertical impact, with the principal measurement being the compressive load in the lumbar spinal column, with a regulatory limit of 1500 lb.

Screw piles need to be upscaled for offshore use e.g. being an alternative foundation and anchor form for offshore floating wind turbines, although the high demand of vertical installation forces could prevent its application if conventional pitch-matched installation is used. Recent studies, using numerical and centrifuge physical tests, indicated that the vertical installation force can be reduced by adopting over-flighting which also improved axial uplift capacity of the screw pile. The current study extends the scope to axial cyclic performance with respect to the installation approach. Us

A semi-empirical elasto-plastic constitutive model with a hyperbolic stress-strain curve was developed with the goal of predicting the seismic compression of unsaturated sands in the funicular regime of the soil-water retention curve (SWRC) during undrained cyclic shearing. Using a flow rule derived from energy considerations, the evolution in plastic volumetric strain (seismic compression) was predicted from the plastic shear strains of the hysteretic hyperbolic stress-strain curve. The plastic volumetric strains are used to predict the changes in degree of saturation from phase relationships

The pipeline industry uses over 8,000 large bore engines in gas transmission/compression service". These engines are typically gas fueled and spark ignited. Some early versions of the engines are piston scavenged, but most are turbocharged. Some models, especially those equipped for lean burn operation, utilize pre-combustion chambers for enhanced ignition. Typically, the gaseous fuel is admitted directly into the top of the engine combustion chamber by a cam-operated, mechanical gas admission valve (MGAV). The MGAV is operated by an engine driven cam, cam follower, push rod, and rocker assemb
