Governing Equation Identification of Nonlinear Single Degree-of-Freedom Oscillators With Coulomb Friction Using Explicit Stick and Slip Temporal Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The friction force at joints of engineering structures is usually unknown and not directly identifiable. This contribution explores a procedure for obtaining the governing equation of motion and correctly identifying the ...
Reshape of the Bistable and Multistable Properties of Conical Structures Through Integrated Modification of Local Cross Section
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multistable structures can maintain multiple steady states without additional loads. However, the presence of geometric and material nonlinearities in multistable structures adds complexity and difficulty to their optimal ...
A Finite Element Based Comparative Study of Lumbosacral Pedicle Screw Fixation and Artificial Disc Replacement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of this is to evaluate the biomechanical performance of double-level semirigid pedicle screw fixation and artificial intervertebral disc replacement in lumbar spine. Ti6Al4V and CFR-PEEK material are used for pedicle ...
Implementation of Precision Machine Tool Thermal Error Compensation in Edge-Cloud-Fog Computing Architecture

Manufacturing-Cost-Driven Topology Optimization of Welded Frame Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents a method for the topology optimization of welded frame structures to minimize the manufacturing cost. The structures considered here consist of assemblies of geometric primitives such as bars and plates ...
A New Strain Energy Function Representing the Passive Behavior of the Myocardium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Classical models for the passive myocardium, such as the Fung and Holzapfel–Ogden models, are known to have high degeneracy as well as numerous mechanical and mathematical limitations, preventing their utility in microstructural ...
Numerical Modeling and Analysis of Energy-Assisted Compression Ignition of Varying Cetane Number Jet Fuels for High-Altitude Operation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics (CFD) simulations are performed to study the potential of energy-assisted compression ignition (EACI) strategy for enabling ignition and enhancing combustion of different cetane number jet fuels ...
Computational Analysis of Air/Mist Film Cooling Using a Sweeping Jet Fluidic Oscillator–Part I: Sweeping Air-Only Jet With Detailed Analysis of Vortex Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The sweeping jet can be a promising candidate in film cooling applications since it has a large lateral jet spreading which can be considered an advantage when compared to the regular steady jet film cooling. Fluidic ...
Performance Study of Photovoltaic/Thermal Collector System for Cold Production by Adsorption in a Mediterranean Climate: Foodstuffs Preservation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents a numerical study on the performance of a stand-alone adsorption cooling system based on the silica gel/water couple driven by hybrid photovoltaic/thermal (PVT) collectors. This system is intended for ...
