Limit Analysis of Active and Passive Mechanisms of Shallow Tunnels in Nonassociative Soil with Changing Water Table
Publisher: American Society of Civil Engineers
Abstract: The evaluation of the failure mechanism of a shallow tunnel is very significant in geotechnical engineering. In this literature an analytical methodology for determining the plane strain limit failure mechanism for a shallow ...
Atomic Study on Copper–Copper Bonding Using Nanoparticles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermocompression bonding of copper to copper using copper nanoparticles is studied using molecular dynamics. The bonding interface formation process is investigated frst. For the bonding process, the effects of temperature ...
Study of the Moisture Equilibrium of Highway Expansive Soil Embankments
Publisher: American Society of Civil Engineers
Abstract: To investigate the moisture equilibrium of expansive soil embankments, a series of stress-dependent soil-water characteristic curve (SWCC) tests, one-year field monitoring on a trial covered expansive soil embankment, and ...
A Model for the Fast Determination of Modal Sound Transmission of Large Rectangular Opening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The existence of openings affects the sound insulation performance of structures significantly. The determination of sound transmission through large rectangular openings is often time-consuming, because of the large number ...
Finite Element Limit Analysis of the Bearing Capacity of Strip Footing on a Rock Mass with Voids
Publisher: American Society of Civil Engineers
Abstract: Finite element limit analysis (FELA) was used to investigate the bearing capacity of strip footing on a rock mass with single or multiple continuous voids. The underlying rock mass was assumed to have perfect plasticity ...
Thermal Resistance Analysis of Sn Bi Solder Paste Used as Thermal Interface Material for Power Electronics Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To promote heat dissipation in power electronics, we investigated the thermal conduction performance of SnBi solder paste between two Cu plates. We measured the thermal resistance of SnBi solder paste used as thermal ...
Quantification of Age Related Tissue Level Failure Strains of Rat Femoral Cortical Bones Using an Approach Combining Macrocompressive Test and Microfinite Element Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bone mechanical properties vary with age; meanwhile, a close relationship exists among bone mechanical properties at different levels. Therefore, conducting multilevel analyses for bone structures with different ages are ...
Bacterial Communities in Marine Aerosols Revealed by 454 Pyrosequencing of the 16S rRNA Gene
Publisher: American Meteorological Society
Abstract: lthough bacteria are an important biological component of aerosol particles, studies of bacterial communities in remote marine aerosol are largely lacking. In this study, aerosol samples were collected over the western ...
Delaying Effect of Extracellular Polymer Substances on Fluid Mud Consolidation and Application for Nautical Depth
Publisher: American Society of Civil Engineers
Abstract: Microorganisms have been used to delay fluid mud consolidation and to keep fluid mud navigable. However, bacteria and extracellular polymer substances (EPSs) that delay sediment consolidation have not been studied widely, ...
Preparation of SiC-Coated Silicon Nanofiber/Graphite Composites as Anode Material for Li-Ion Batteries by the Chemical Vapor Deposition Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Si material has huge lithium storage capacity, but its huge volume changes during charging and discharging making it difficult to use. However, by using nano-sizing Si material and building a coating structure can effectively ...
