RISFatigue Crack Growth Rate in 63Sn37Pb Solder Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue crack growth rate (FCGR) was determined in shear (Mode II) on notched 63Sn37Pb solder joints at room temperature. The FCGR data correlated reasonably well with the expression da/dN = ...
Assessment of Two- and Three-Scale k–ε Models for Rotating Cavity Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three-scale k–ε turbulence model was recently developed for complex flows such as the rotor–rotor and rotor–stator cavities found in gas turbine engines. The three-scale model is a logical ...
Mobility of Single-Loop N-Bar Linkage With Active/Passive Prismatic Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Single-loop N-bar linkages that contain one prismatic joint are common in engineering. This type of mechanism often requires complicated control and, hence, understanding its mobility is very ...
The Design of a New Metal Forming Press with Controllable Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Metal forming press is one of the most commonly used manufacturing machines. Every day, millions of parts are produced by metal forming ranging from battery caps to automotive body panels. ...
Plastic Deformation Kinetics of Eutectic Pb-Sn Solder Joints in Monotonic Loading and Low-Cycle Fatigue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The deformation kinetics of near-eutectic Pb-Sn alloys in monotonic and cyclic loading in shear at 300K were investigated by determining the stress exponent n in the Dorn equation using several ...
Plastic Deformation Kinetics of 95.5Sn4Cu0.5Ag Solder Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The plastic deformation kinetics of 95.5Sn4Cu0.5Ag solder joints were determined in monotonic loading shear over the temperature range of 25°–150°C using three types of tests: (a) constant ...
On Hybrid Boundary Control of Flexible Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Simple proofs are presented which show that hybrid boundary control systems are asymptotically, but not exponentially, stable. The asymptotic rates of decay of eigenvalues are determined analytically ...
Free and Forced Vibration of an Axially Moving String With an Arbitrary Velocity Profile
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The exact response of an axially moving string with an arbitrary velocity profile is determined under general initial conditions and external excitation. In terms of the curvilinear characteristic ...
A New Type of Controllable Mechanical Press: Motion Control and Experiment Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is the second part of our study on designing a new type of metal forming press. In the first part of the study (, and , 2003, ASME J. Mech. Des., 125(3), pp. 582–592), a new ...
Asymptotic Distribution of Eigenvalues of a Constrained Translating String
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new spectral analysis for the asymptotic locations of eigenvalues of a constrained translating string is presented. The constraint modeled by a spring-mass-dashpot is located at any position ...
