RISDensification Forming of Alumina Powder—Effects of Power Law Creep and Friction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High temperature forming processes of alumina powder compacts were analyzed by using constitutive equations which are capable of predicting densification and grain growth under diffusional creep ...
High Temperature Densification Forming of Alumina Powder—Constitutive Model and Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Densification and grain growth of alumina powder compacts were investigated under pressureless sintering, sinter forging, and hot pressing. A set of constitutive equations by Kwon et al. was ...
Strain Hardening Response of Sintered Porous Iron Tubes With Various Initial Porosities Under Combined Tension and Torsion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elastic-plastic strain hardening responses of sintered porous iron are investigated. By using the yield function of Kim, two sets of constitutive equations are obtained from the constitutive ...
An Analysis of Void Deformation Caused by Power Law Creep and Diffusion Enhanced by Mechanical Stress in HIP Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A dominant deformation mechanism in an isostatic pressure sintering process of a powder compact is known as power law creep. The deformation of a pore was predicted from the existing stress ...
Elastic-Plastic Response of Sintered Porous Iron Under Uniaxial Strain Cycling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elastic-plastic responses of porous iron under uniaxial strain cycling between two fixed values of strain are investigated. A special set of constitutive equations is formulated by including ...
Cavitation in an Extremely Limited Flow Through Very Small Orifices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to clarify the role of cavitation nuclei upon inception, the behavior of inception was carefully investigated in an extremely limited water flow through very small orifices less than ...
Engineering Characteristics of Rubber-Added Lightweight Soil as a Flowable Backfill Material
Publisher: American Society of Civil Engineers
Abstract: This study investigated the engineering characteristics of rubber-added lightweight soil (RLS), which consists of dredged soil, crumb rubber, and bottom ash. RLS is considered to be environmentally friendly because it ...
Flow-Induced Bending of Rectangular Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analysis of flow-induced bending of rectangular plates simply supported on two sides and free on the leading and trailing edges, with viscous entry flows differing in flow rate on top and ...
Analysis for Cold Die Compaction of Stainless-Steel Powder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Densification behavior of 316L stainless-steel powder under die pressing was studied. The friction effects between the powder and the die wall under different die pressing modes were also ...
Novel Hub Fins for Axial Flow Fans for the Enhancement of Impingement Heat Transfer on a Flat Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thermal characteristics of exit flow issued from an axial fan widely used for impingement cooling of power electronics are experimentally studied. A new fan configuration is proposed to ...
