RISEffect of Temperature Fluctuation on Creep and Failure Probability for Planar Solid Oxide Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The creep and failure probability of a planar solid oxide fuel cell (SOFC) through a duty cycle is calculated by finite element method (FEM) and Weibull method, respectively. Two sealing methods, namely, rigid seal and ...
Evaluation of Through-Thickness Residual Stresses by Neutron Diffraction and Finite-Element Method in Thick Weld Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Through-thickness distributions of the welding residual stresses were studied in the range of 50–100 mm thick plates by using finite-element modeling (FEM) and neutron diffraction measurements. In order to simulate the ...
Constraint Dependent J R Curves of a Dissimilar Metal Welded Joint for Connecting Pipe Nozzle of Nuclear Pressure Vessel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the JR curves of two cracks (A508 HAZ crack 2 and A508/Alloy52Mb interface crack 3) located at the weakest region in an Alloy52M dissimilar metal welded joint (DMWJ) for connecting pipenozzle of nuclear ...
Neutron Diffraction Measurement and Numerical Simulation to Study the Effect of Repair Depth on Residual Stress in 316L Stainless Steel Repair Weld
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Welding is often used to repair the defects in pressure vessels and piping, but residual stresses are generated inevitably and have a great effect on structure integrity. According to the defect size, different repair depth ...
