RISModeling the Instability of Carbon Nanotubes: From Continuum Mechanics to Molecular Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A hybrid continuum mechanics and molecular mechanics model is developed in this paper to predict the critical strain, stress, and buckling load of the inelastic buckling of carbon nanotubes. ...
Generating Dispatching Rules for the Interrupting Swap-Allowed Blocking Job Shop Problem Using Graph Neural Network and Reinforcement Learning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The interrupting swap-allowed blocking job shop problem (ISBJSSP) is a complex scheduling problem that is able to model many manufacturing planning and logistics applications realistically by addressing both the lack of ...
Effects of Nanoalumina and Graphene Oxide on Early-Age Hydration and Mechanical Properties of Cement Paste
Publisher: American Society of Civil Engineers
Driving Forces and Transportation Efficiency in Water Transportation Through Single-Walled Carbon Nanotubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the concept of an energy pump, water transportation in a carbon nanotube (CNT) is studied by molecular dynamics simulations. The influences of CNT pretwist angle, water mass, environmental ...
Mitigation Methods of Climate Change Impact on the Cooling Load of Public Residential Buildings in Singapore
Publisher: American Society of Civil Engineers
Abstract: Buildings have time-varying interactions with the local climate condition for the heating or cooling systems; changes of the surrounding climate condition affect building energy consumption. Based on the thermal envelope ...
Influence of Nanolimestone on the Hydration, Mechanical Strength, and Autogenous Shrinkage of Ultrahigh-Performance Concrete
Publisher: American Society of Civil Engineers
Abstract: The influence of nanolimestone/nanoCaCo3 (NC) on the properties of ultrahigh-performance concrete (UHPC) cured at standard and heat conditions was experimentally investigated. The NC was used at ratios of 1, 2, and 3% as ...
Reinforcing Effects of Graphene Oxide on Portland Cement Paste
Publisher: American Society of Civil Engineers
Abstract: In this experimental study, the reinforcing effects of graphene oxide (GO) on portland cement paste are investigated. It is discovered that the introduction of 0.03% by weight GO sheets into the cement paste can increase ...
Segmentation of Additive Manufacturing Defects Using U-Net
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) provides design flexibility and allows rapid fabrications of parts with complex geometries. The presence of internal defects, however, can lead to the deficit performance of the fabricated part. ...
