RISFlying Height Measurement on Al2O3 Film of a Magnetic Slider
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flying height has been successfully measured on the Al2 O3 film of a magnetic slider by using a specially developed ellipsometer, a reflectometer, and an intensity based interferometric flying ...
Experimental Investigation of Excitation Strategies for Erosion by Cavitation Histotripsy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cavitation histotripsy has been applied to the disintegration on the surface of soft tissue in a well-controlled manner. Its performance was assumed to be determined by the acoustic pressure alone. Long pulse duration with ...
Predicting the Coefficient of Friction in Sliding-Rolling Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the development of a dimensionless empirical formula for calculating the coefficient of friction in sliding-rolling steel on steel contacts under different operating conditions ...
Constitutive Modeling of Coarse-Grained Materials Incorporating the Effect of Particle Breakage on Critical State Behavior in a Framework of Generalized Plasticity
Publisher: American Society of Civil Engineers
Abstract: Coarse-grained materials (CGMs), including gravel, ballast, and rockfill material, exhibit a complicated stress-strain-volume change behavior, which is state dependent and influenced by considerable particle breakage even ...
Failure Mechanism of Expansion Joints in a Suspension Bridge
Publisher: American Society of Civil Engineers
Abstract: Premature failure of expansion joints is a concern for bridge owners. After opening to traffic, the Jiangyin suspension bridge experienced frequent damage in expansion joints, and the problem remained unsolved even after ...
A Model of Slider/Disk Interface Wear for Proximity Recording
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Slider/disk interface wear is inevitable for ultra-low flying hard disk drives and is the central issue for proximity recording. While disk wear has been addressed in the literature, slider ...
The Spin-Off of Particles on a Magnetic Disk
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A spin-off ratio is used in this study to assess the repelling capability of a disk surface to thermal asperity for MR drives. A test methodology is described and a simple model is developed. ...
Experimental and Numerical Prediction of Collapse of Flatbar Stiffeners in Aluminum Panels
Publisher: American Society of Civil Engineers
Abstract: Flatbar stiffeners are attractive in stiffened plates from a fabrication point of view. Flatbars are susceptible to torsional buckling and collapse. Current approaches to assess torsional buckling strength are uncertain. ...
Analytical Solutions for Simply Supported Viscously Damped Double-Beam System under Moving Harmonic Loads
Publisher: American Society of Civil Engineers
Abstract: In this paper, the dynamic response of a simply supported viscously damped double-beam system under moving harmonic loads is investigated. The double-beam system consists of two elastic homogeneous isotropic beams, which ...
Quenching Phenomenon of a Time-Fractional Kawarada Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we introduce a class of time-fractional diffusion model with singular source term. The derivative employed in this model is defined in the Caputo sense to fit the conventional initial condition. With assistance ...
