RISLife Prediction of Notched Specimens Using Multiaxial Surface and Subsurface Strain Analyses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multiaxial fatigue life prediction analyses are applied to notched specimens subjected to high strain constant amplitude loading. The specimens are made from isotropic and anisotropic batches of ...
Flow Phenomena in Compressor Casing Treatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An axial skewed slot casing treatment has been tested over the tips of an isolated low-speed rotor with a hub-tip ratio of 0.4. An improvement in stall margin of 22 percent at nominal ...
An Engineering Approach to the Prediction of Creep Crack Growth
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with assessing the integrity of cracked engineering components which operate at elevated temperatures. Fracture mechanics parameters are discussed for describing creep crack ...
Modeling and Measurement of Residual Stresses in a Steel Vessel Containing Glass
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Residual stresses in a stainless steel vessel containing glass have been evaluated using measurements and numerical simulation. High-level nuclear wastes are often vitrified in glass cast in ...
The Effect of Dimethylsulfoxide on the Water Transport Response of Rat Hepatocytes During Freezing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Successful improvement of cryopreservation protocols for cells in suspension requires knowledge of how such cells respond to the biophysical stresses of freezing (intracellular ice formation, water ...
An Inverse Method for Reconstruction of the Residual Stress Field in Welded Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Welding process is widely used in manufacturing of many important engineering components. For such structures, the most important problem is the development of residual stresses and distortion ...
A Comparison of Two- and Three-Dimensional Fracture Assessments in the Presence of Residual Stresses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of various assumptions on the modeling of cleavage fracture in the presence of residual stresses was investigated. Analyses were undertaken for modified single edge notched bend ...
Creep Relaxation of Residual Stresses Around Cold Expanded Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The cold expansion of fastener holes in aircraft components is a standard technique to improve fatigue life. There is concern that the beneficial residual stresses arising from cold expansion ...
Measurement of Residual Stresses in a Type 316H Stainless Steel Offset Repair in a Pipe Girth Weld
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents measurements of the in-plane residual stress components through the wall of a 218mm long, 26mm deep repair weld, offset by 7mm from the centerline of a girth weld joining ...
Measurement and Prediction of the Residual Stress Field Generated by Side-Punching
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Side-punching is proposed as a method of introducing a well-defined residual stress field into a laboratory-sized test specimen. Such a specimen may subsequently be used to assess the influence ...
