RISAn Engineering Approach to Hertzian Contact Elasticity—Part I
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Results given in this paper are threefold. In the case of Hertzian line contact, a new load/deformation relationship is derived analytically and use is made of the thickness of the outer race ...
Sui, F., and Ichchou, M. N., 2004, “Prediction of Time-Varying Vibroacoustic Energy Using a New Energy Approach” (ASME J. Vib. Acoust. 126, 184–189)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses the issue of transient structural dynamics in the higher-frequency range by an energetic approach. Its main purpose is to propose an alternative equation [Eq. (10) of the ...
Simulations of Channel Flows With Effects of Spanwise Rotation or Wall Injection Using a Reynolds Stress Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Simulations of channel flows with effects of spanwise rotation and wall injection are performed using a Reynolds stress model. In this work, the turbulent model is extended for compressible ...
An Engineering Approach to Non-Hertzian Contact Elasticity—Part II
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Roller/race misalignment and deformation are used for calculating analytically the pressure distribution along the roller/race contact and the final roller/race load and moment. Use is made of ...
Theoretical Modeling of Creep Behavior of Bellows and Some Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of bellows expansion joints is an effective method to rationalize various piping systems in industry. In the structural design, the requirements for preventing failures such as ratcheting, ...
An On-line Condition Monitoring and Diagnosis System for Feed Rolls in the Plate Mill
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An on-line condition monitoring and diagnosis system for feed rolls was developed for providing early warnings of malfunctions so as to avoid great losses resulting from unexpected shutdown of ...
Numerical Study of Cavitation in Cryogenic Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerical simulations of cavitation in liquid nitrogen and liquid hydrogen are presented; they represent a broader class of problems where the fluid is operating close to its critical temperature ...
Numerical Investigation of Swirling Flow in Annular Diffusers With a Rotating Hub Installed at the Exit of Hydraulic Machines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A single sweep method for the solution of Navier-Stokes equations is used for numerical investigation of flow in annular diffusers formed by a cylindrical casing and a converging conical hub, ...
Simulations of Cavitating Flows Using Hybrid Unstructured Meshes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new multi-phase model for low speed gas/liquid mixtures is presented; it does not require ad-hoc closure models for the variation of mixture density with pressure and yields thermodynamically ...
Discontinuities in the Sensitivity Curves of Laminated Cylindrical Shells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The discontinuity in the sensitivity of laminated cylindrical shells is investigated via the initial post-buckling analysis. A general procedure for sensitivity, based on Koiter’s parameters and ...
