... concentration" and "macro-scale strain dispersion" which lead to a large work hardening and a large uniform elongation without deformation localization. INTRODUCTION Over many years, ultra-fine grained (UFG) metals have been proved to be attractive structural materials because of superior strength (E.Ma...

... elongation is 12%. Therefore, the optimal combination of FSW parameters and tool geometry were set for the butt joint and the influence of the FSW parameters on the properties of the Cu-Al dissimilar materials joints was defined. The technology of Impulse Friction Stir Welding (IFSW) was implemented...

... of this paper is to assess the changes in umbilical cable parameters like change in resistance, electrical insulation, fibre optic losses, cable elongation etc. which influence the reliability and safety of operation in off shore applications. Specific tensile load tests on the sample length of umbilical cables...

Axial elongation and circular expansion can be found as the temperature and pressure gets higher, which may cause the change of the axial stiffness and aggravate the bucking of flexible pipes. Also...

The Rules of Russian Maritime Register of Shipping establish a limit value for elongation of diagonals, which is 35 mm (Rules for the Classification and Construction of Sea-Going Ships...

... Abstract Transmission pipelines that cross regions prone to ground movement events are subject to large longitudinal strains and plastic circumferential elongation as the pipeline experiences alignment changes resulting from differential ground movement. The design trend for new pipelines...

... ABSTRACT We developed a mathematical model for accurately calculating the pipe-in-pipe riser tension and elongation in Part A of the paper. In this Part B, we focus on finite element modeling of the multi-string riser system. The simulations are performed using two widely used riser analysis...
