... inspection had already been arrested if they did not penetrate the wall thickness. It is effective to consider the crack arrest scenario for design and integrity assessment of cracked components under high-cycle thermal fatigue loading. 09 10 2009 06 06 2011 19 10 2011 19 10 2011...

... machined in the tubesheet hole on the distributions and magnitudes of the radial deformation of tube walls and the residual stresses along the expanded length of the tube and in the transition zone. The results have revealed the presence of tensile and compressive residual axial and hoop stresses...

... wall cylindrical vessel with semielliptical ends. Each time an explosive charge is fired in the vessel, that vessel is submitted to a number of deformation cycles. A series of strain gauges measures the deformation of the vessel walls. Experimental peak strains and vibration frequency can be compared...

... shell, particularly local wall thinning and thermal hot spot, is investigated. The derived solutions are based on identifying the regions in the damaged component that directly participate in the plastic action (kinematically active). The concepts of reference volume and decay length are employed...

...Alexey Velikorodny; Graham Duck; Peter Oshkai Digital particle image velocimetry was applied to investigate turbulent flow of air between a flexible wall and a rigid surface containing a backward-facing step (BFS). The inflow condition corresponded to a Coanda jet issuing from a nozzle...

...Xian-Kui Zhu; Brian N. Leis This paper investigates plastic collapse failure behavior and analytical assessment methods for unequal wall transition joints in transmission pipelines. The objective is to (i) validate the plastic-collapse-based code requirements that were determined by the early lower...
