In this paper, the effect of autofrettage process parameters on the ultimate pressure that functionally graded spherical vessel can tolerate are investigated. FGM properties and autofrettage pressure are considered as important parameters. Assumptions are variation of properties of FGM in radial direction, the residual stress in the absence of Bauschinger effect with the operation of variable m...

The dramatic increasing of sea-freight container transportations and the developing trend for using containers in the multimodal handling systems through the sea, rail, road and land in the present market cause some challenges to the general managers of container terminals such as increasing demand, competitive situation, new investments and expansion of new activities and the need to use new m...

This paper presents a combined experimental–analytical investigation of coal strain development under fluctuating applied hydrostatic stress. The laboratory setup mimics the isotropic volumetric compaction burial–uplift cycles in absence tectonic Special emphasis is placed on corresponding permeability evolution strata. Our results show that stress–strain path exponential, approaching linear re...

Due to the demand for oil production in varying water depth regions, advantage of flexible buoyant conduits has led an increase bonded marine hoses fluid transfer and (un)loading operations. The system is dependent on floating offshore structures (FOS). This paper presents overview different systems sustainable operations via FOS, such as Single Point Mooring (SPM) systems. SPMs are component a...

the global environmental concerns have put the light weighting of structures on the fore front of the research in transportation industry. among other light weight alloys, the transportation industry is considering magnesium intensive light body-in-white structure in automotive applications. although the research in modeling technique areas is very active, a suitable practical model mimicking t...

Abstract With the development of intralogistics technology in factories, multi-AGV scheduling is still an important problem that needs to be solved by control system. Aiming at path planning and automated guided vehicle (AGV) factory loading unloading work, this paper designs a two-way dual map construction method suitable for factory, introduces different weight right path, uses “simulated roa...
