RISExperimental Research on Flow Instability Mechanism of a Highly Loaded Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance and stable operating range of compressors are critical for the efficient operation of various turbomachinery systems. To reveal the flow instability mechanism of a high-speed and high-loaded compressor, a ...
Comparative Analysis of Bursting Pressure Prediction Methods for Steam Generator Tube With Volume Defect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper compares the difference and accuracy of bursting pressure prediction based on the flow stress σf prediction method, plastic collapse prediction method, and ductile damage model prediction method in Inconel 690 ...
Estimation of Minimum Design Metal Temperature by MDMT Curve and Correlations of Charpy Impact and Fracture Toughness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Charpy impact specimens are preferred to characterize the deterioration of steel in irradiation surveillance program in nuclear industry. But the fracture toughness cannot be acquired by the Charpy impact experiment directly. ...
Assessing Toughness Levels for Nuclear Containment Vessels Steel to Determine the Need for Postweld Heat Treatment Based on the Master Curve Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a minimum toughness assessment method of exempting postweld heat treatment (PWHT) based on the master curve method is proposed to replace the current method of determining whether to perform PWHT by material ...
Theoretical and Experimental Research on Designed Bursting Pressure of Ultrahigh Pressure Rupture Disk
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rupture disk safety device plays an important role as the last safety barrier to prevent catastrophic overpressure in chemical vessels. In this article, a burst pressure calculation method of ultrahigh pressure rupture ...
Study on the Effect of Pressure Rise Rate on the Burst Pressure and Failure Regularity of Conventional Domed Rupture Disk
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rupture disk is an important safety relief device whose bursting at set pressure is essential to protect pressure equipment. However, the existing standards and research still lack the system regularity study of the pressure ...

Study on Autofrettage Process Parameters Selection and Methods Improvement of Hoop Wrapped Composite Vessel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Current selection criteria for autofrettage pressure in hoop wrapped composite vessels are inadequately defined, critically lacking consideration of axial structural safety and fatigue life requirements. To address ...
Fatigue Life Assessment of High-Pressure Hydrogen Storage Vessel Enhanced by Crack Grinding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Fatigue life of high-pressure hydrogen storage vessel with design pressure of 45 MPa and 99.9 MPa was investigated. The feasibility of improving fatigue life with crack grinding strategy was verified. First, ...
Migration of Rectangular Mining Pit Composed of Uniform Sediments
Publisher: American Society of Civil Engineers
Abstract: Sand and gravel mining from riverbeds is a major supply of construction materials. A mining pit in a riverbed is very unstable and subject to scouring and deposition, which results in migration of the pit. A series of ...
