Numerical Investigation of Residual Stresses in YBCO/CeO2/YSZ/CeO2/Ni Architextured Materials for Coated Conductors

NUMERICAL INVESTIGATION OF RESIDUAL STRESSES IN YBCO/CeO2/YSZ/CeO2/Ni ARCHITEXTURED MATERIALS FOR COATED CONDUCTORS

AbstractIn this study, the stress analysis of YBCO/CeO2/YSZ/CeO2/Ni architextured materials under cryogenic conditions was carried out for coated conductor applications. YBCO/CeO2/YSZ/CeO2 multilayer films were fabricated on Ni tape substrate using reel-to-reel sol-gel and Pulse Laser Deposition (PLD) systems. The microstructural evolution of high temperature superconducting YBCO film and buffe...

Residual Stresses in Case Hardened Materials

Fatigue behavior of case hardened parts depend to a great extent on the type of residual stresses developed in the components. Topography and metallurgical effects were the two elements which contribute much to surface integrity. Micro hardness of the gas carburized (EN 33 and EN 36) and Induction hardened (AISI 1040 and AISI 6150) specimens obtained during experiments, showed that there was gr...

Numerical Analysis of explosion effects on the redistribution of residual stresses in the underwater welded pipe

Structural health monitoring of cracked structures is one of beloved subject of researchers recently. Consider of crack behavior in the water and energy pipeline is important because of environmental problems. In this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. For this purpose, three- dimensional parametric model of cracked ...

Numerical modelling and experimental investigation on welding residual stresses in largescale tubular Kjoints

Numerical Study on Residual Thermal Stresses in Carbon Fibre Pullout

This paper investigated the effect of residual thermal stresses on carbon fibre pullout by using cohesive zone modelling. The finite element method was applied to analyse the residual thermal stress components along the interface between the fibre and matrix due to curing. A comparison study on the anisotropic and isotropic material properties are considered using four typical carbon fibres, T3...
