RISVery Large Eddy Simulation of Aero-Thermal Performance in Squealer Tip Gap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To improve the resolution accuracy and get deep insight into the flow structures in squealer tip gap, the very large Eddy simulation (VLES) method was implemented into the commercial computational fluid dynamics (CFD) ...
Fracture Analysis of Sharp Notches Under Mode III Loading: A Local Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, an attempt is made to propose a local approach for fracture analysis of sharp notches under Mode III loading. Under the assumption that the stress concentration factor eigenvalue k* for V-notches under Mode I loading proposed by Yan...

Large-Scale Swelling in the Plane Stress Fracture of Hydrogels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. When a cracked hydrogel sample is stretched, a swelling zone around the crack tip occurs due to water migration. As time evolves, the swelling zone grows, from the small-scale swelling to the large-scale swelling. ...
A Local Approach for Fatigue Life Analysis of Notched Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. From the author's previous study, it is sure that the local approach for fracture analysis of notched components under static loading proposed by the author established on the basis of linear elastic mechanics ...
Effect of Yield Surface Curvature on Local Necking in Biaxially Stretched Sheets in Porous Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a recently proposed material model (Sun model) that is based on the lower bound approach of plasticity is extended by introducing a family of dilatant plasticity theories. The ...
Numerical Methodology to Evaluate the Effects of Bone Density and Cement Augmentation on Fixation Stiffness of Bone Anchoring Devices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bone quality is one of the reported factors influencing the success of bone anchors in arthroscopic repairs of torn rotator cuffs at the shoulder. This work was aimed at developing refined numerical methods to investigate ...
An Efficient and Accurate Numerical Method of Stress Intensity Factors Calculation of a Branched Crack
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the analytical solution of Crouch to the problem of a constant discontinuity in displacement over a finite line segment in an infinite elastic solid, in the present paper, the crack-tip ...
An Effective Numerical Approach for Multiple Void-Crack Interaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a numerical approach to modeling a general system containing multiple interacting cracks and voids in an infinite elastic plate under remote uniform stresses. By extending ...
