A Study of a New Bidirectional Pressure-Regulating Valve for Hydraulically Interconnected Suspension Systems
(The American Society of Mechanical Engineers (ASME), 2020)Due to inevitable inner leakage in hydraulic circuits and structural limits of a hydraulically interconnected suspension (HIS) system, pressure difference between HIS's two independent hydraulic circuits leads to vehicular ... -
The Effect of a Three-Dimensional Quarter-Circle Corner Crack on the Stress Intensity Factors of a Nonaligned Semi-Elliptical Surface Crack in an Semi-Infinite Solid Under Uniaxial Tension
(The American Society of Mechanical Engineers (ASME), 2020)The Fitness-for-Service (FFS) approach requires the evaluation of the mutual impact of nonaligned, multiple cracks on each other. As such, initially one must resolve whether existing, nonaligned, parallel cracks in the ... -
Assessment of Interacting Corrosion Defects in Thin-Walled Pipes
(The American Society of Mechanical Engineers (ASME), 2020)Corrosion in pipes is usually found in the form of closely spaced defects, which eventually reduce the pipe pressure carrying capacity and piping planned useful life. Codes and standards have been developed to evaluate the ... -
Brittle Crack Arrestability and Inverse Fracture in DWTT
(The American Society of Mechanical Engineers (ASME), 2020)The drop-weight tear test (DWTT) has been widely used to evaluate the resistance of linepipe steels against brittle crack propagation, and the shear area fraction SA% in the DWTT has been adopted in the requirement for the ... -
The Influence of Multiaxial Stress Relaxation on Component Creep Damage Accumulation
(The American Society of Mechanical Engineers (ASME), 2020)Unless inelastic analysis is used, high temperature codes base creep relaxation on the start-of-dwell equivalent stress, which relaxes according to a uniaxial creep law. Elastic follow-up is also included. This approach ... -
The Effect of Porosity on Elastic Stability of Toroidal Shell Segments Made of Saturated Porous Functionally Graded Materials
(The American Society of Mechanical Engineers (ASME), 2020)This research deals with the stability analysis of shallow segments of the toroidal shell made of saturated porous functionally graded (FG) material. The nonhomogeneous material properties of porous shell are assumed to ... -
Impact Pressure Evaluation of Water Jet Peening on Typical Concave Surfaces: Theoretical and Finite Element Analysis
(The American Society of Mechanical Engineers (ASME), 2021)Water jet peening (WJP), a surface modification technique, can use the impact pressure induced by shock waves to introduce compressive residual stress in the surface of metal parts, thereby improving the fatigue life of ... -
Natural Frequency Measurements of the Fluid-Elastic-Coupled Shell Plate Vibration in a Large-Sized Cylindrical Steel Tank by Microtremor Observations
(The American Society of Mechanical Engineers (ASME), 2021)Naturally occurring microtremor observations measured the natural frequencies of the fluid-elastic-coupled shell plate vibration (bulging) in a large flat-bottomed cylindrical steel tank with a capacity of 125,000-m3. Five ... -
Experimental Flow-Induced Vibration Analysis of the Crossflow Past a Single Cylinder and Pairs of Cylinders in Tandem and Side-by-Side
(The American Society of Mechanical Engineers (ASME), 2020)Flow-induced vibration of a single cylinder and two cylinders in tandem and side-by-side configurations is experimentally investigated in this paper in the subcritical regime. The natural frequency of the system varied ... -
Analysis of Explosion Load in a Cylindrical Container With Sand Bottom
(The American Society of Mechanical Engineers (ASME), 2020)Explosion containment vessels are widely used in many fields. Here, the detonation impact load of explosives in a cylindrical closed explosion containment vessel partially filled with sandy soil was studied. A three-dimensional ... -
The Branching Redesign Technique Used for Upgrading Steel-Pipes-Based Hydraulic Systems: Re-Examined
(The American Society of Mechanical Engineers (ASME), 2020)The branching technique demonstrated an effective ability to attenuate severe hydraulic-head magnitudes into existing steel-pipes-based hydraulic systems. However, there was no detailed exploration of circumferential-stress, ... -
