“…Under different experimental conditions, the variation rule of normal displacement with shear displacement varies. At 200 kPa, the volumetric characteristics of each cycle stage 1 are mainly manifested as shear expansion, while the soil at stage 2 , 3 , and 4 exhibits volumetric characteristics of first shear shrinkage and then shear expansion. At 1100 kPa and 2400 kPa, the volumetric deformation characteristics of siliceous sand are mainly characterized by shear expansion in the stage 1 of the first cycle, except for small shear shrinkage in the initial stage of the first cycle.…”

“…Sand is a common and representative geotechnical medium [1,2], which is widely distributed in coastal zones, rivers, and foothills due to geographical conditions such as terrain and sedimentary environment. In recent years, with the rapid development of economy, more and more energy projects and high-speed transportation projects are built along rivers and coastal areas, such as offshore wind turbines [3,4], offshore drilling platforms, sea crossing bridges, etc. These projects need to have high overturning resistance and bear large superstructure loads.…”

It is of great significance to deeply understand the stress damage mechanism of the pile–soil interface under cyclic loading for the safety control of engineering entities. Large-scale self-developed shear equipment was used to conduct cyclic shear tests of the interface between steel and siliceous sand, and the macroscopic shear characteristics and particle crushing characteristics were analyzed. Finally, the interface micro characteristics were analyzed through numerical simulation. The results indicate that the interface peak shear stress under constant stress conditions mainly exhibits strengthening characteristics, while under constant stiffness conditions it exhibits weakening characteristics. The position of the relationship curve between shear stress and normal stress gradually moves towards the direction of low normal stress as the experiment progresses, and the distance between the curves gradually decreases. The degree of particle breakage increases with the number of cycles but is mainly concentrated in the first few cycles. The principal stress is proportional to the normal stress, and its rotation degree gradually weakens with the normal stress. The contact number of particles at any angle increases with the normal stress.

“…Another study 5 comparatively investigated the onshore and offshore wind characteristics. Guner et al 6 evaluated an offshore wind power plant's sustainability and calculated the LCOE and the payback‐period. For the site selection of offshore wind energy systems, Colak et al 7 studied a GIS‐based multi‐criteria decision analysis by considering the energy and exergy efficiencies of the wind systems.…”

Summary In this study, a solar‐based integrated system is designed and analyzed thermodynamically using the first‐ and second‐law approaches. The sustainable energy island concept is developed to meet the energy and commodity demands of emerging countries in a sustainable manner. The proposed system utilizes an energy island concept where solar energy is the main source and provides electricity, freshwater, and hydrogen by integrating a floating photovoltaic system, a parabolic through collector system, the Cu‐Cl cycle, a multi‐effect desalination unit, and a fuel cell unit in a sustainable fashion. The hydrogen‐based system is used to store energy in the chemical form to compensate for the time when the solar radiation is not available. A transient analysis is carried out to realistically determine the performance of the proposed system in a case study where Northern Cyprus is considered with its annual electricity demand. The proposed system averagely achieves an overall energy efficiency of 14.06% and an overall exergy efficiency of 14.61% while producing a total of 7.1 ton/h of hydrogen, a total of 115.4 ton/h of freshwater, and a total of 362.4 MWp of electricity, respectively.

One of the most important engineering problems today is the optimization of systems and process parameters. Optimization is one of the longest and most costly steps to conclude for many multidisciplinary studies. Numerical analysis has been a widely applied approach to reduce this cost of time and money. In this study, first of all, a gearbox with geometric dimensions is modeled using Matlab commercial package software. The created model was then subjected to finite element analysis via student version of Ansys commercial package. The strength of the system was examined over the stress and deformation values obtained in those analysis. Considering the equivalent von Mises stress values obtained in the study, a maximum 200 MPa design on the gear wheels and a two-fold safe design according to the yield limit was revealed. In addition, a Matlab software that reveals the welding path for the reducer outer sleeve and jib crane has also been produced in this study.
