RISErosion Model for Brittle Materials Under Low-Speed Impacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The erosion of perfectly brittle materials under low-speed impacts is studied by the combination of the Hertzian contact theory and the maximum stress criterion. It is found that the fractional erosion per impact is ...
Effects of Heat Treatment on Sliding Wear and Milling Properties of Ti-6Al-4V Prepared by Selective Laser Melting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ti-6Al-4V titanium alloy manufactured by selective laser melting (SLM) has a unique structure and properties. They offer a higher yield and ultimate tensile strengths but lower ductility than traditionally processed samples. ...
Stability and Hopf Bifurcation of a Fractional-Order Food Chain Model With Disease and Two Delays
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a fractional-order food chain model with disease and two delays is proposed. The existence conditions for a positive equilibrium point are given, and the stability conditions without the effects of delays ...
Multiscale Contribution of Bone Tissue Material Property Heterogeneity to Trabecular Bone Mechanical Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heterogeneity of material properties is an important potential contributor to bone fracture resistance because of its putative contribution to toughness, but establishing the contribution of heterogeneity to fracture risk ...
Cyclic Mechanical Loading Enhances Transport of Antibodies Into Articular Cartilage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The goal of this study was to characterize antibody penetration through cartilage tissue under mechanical loading. Mechanical stimulation aids in the penetration of some proteins, but this effect has not characterized ...
Effects of Grade Designs and Zone Characteristics on Driving Speed in Long Mountainous Freeway Tunnels with Crest Vertical Alignment
Publisher: American Society of Civil Engineers
Abstract: AbstractSafety issues in freeway tunnels are prominent, and how drivers adjust their speed
in response to various grade designs in long mountainous tunnels with crest vertical
curves has not been adequately explored. To ...
Determining the Completed Bridge State of a Self-Anchored Suspension Bridge: A Noniterative Analytical Approach
Publisher: American Society of Civil Engineers
Abstract: Abstract The calculation of the completed bridge state (CBS) for self-anchored suspension bridges
(SASBs) has long been a focal point in both academic and engineering communities.
Most existing methods rely on complex ...
Experimental Investigation of Ignition Transient Phase in Model Supersonic Combustor
Publisher: American Society of Civil Engineers
Abstract: The ignition transient phase in a model supersonic combustor with transverse fuel injection upstream of a cavity flame holder was experimentally investigated. Three types of ignition processes for scramjet startup were ...
Study on Prelithiation Technology of Hard Carbon Electrode Using Stable Metal Lithium Powder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The prelithiation of hard carbon electrode using stable metal lithium powder to compensate the lithium loss during the first lithium insertion is studied in this work. The results show that when the pressure on lithium ...
A Novel Semiemperical Friction Coefficient Model Between Needle and Polyvinyl Alcohol Tissue Phantom and Its Validation by Using Computational Inverse Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Needle–tissue interactive force is vital for developing a virtual simulation and planning system (SPS) and optimizing needle control strategy, wherein the friction coefficient is an important parameter but difficult to ...
