RISFracture Healing Properties of Asphaltic Material under Controlled Damage
Publisher: American Society of Civil Engineers
Abstract: The self-healing properties of asphalt materials present a new means to achieve reliable, durable, and sustainable asphalt pavements through maximizing the effect of microdamage recovery. However, healing (healing of ...
Experimental Study and Numerical Simulation of Propellant Ignition and Combustion for Cased Telescoped Ammunition in Chamber
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cased telescoped ammunition (CTA) is a kind of charge structure with projectile embedded in the cartridge case. The advantages of CTA, compared with concepts using conventional ammunition, are: ...
Experimental and Numerical Investigations on Traveling Charge Gun Using Liquid Fuels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The traveling charge (TC) concept is theoretically capable of producing higher muzzle velocities without a large increase in maximum operating pressure, compared with the conventional charge. This ...
Study on Expansion Process and Interaction of High Speed Twin Combustion-Gas Jets in Liquid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The multilevel stepped-wall and rectangular observation chambers are designed to study the multipoint ignition process and the combustion stability control mechanism of the bulk-loaded liquid ...
Dynamic Behaviors of Delaminated Nanofilms Partly Bonded on Substrates With Sub-Nanoscale van der Waals Dynamic Boundaries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamic behaviors of delaminated nanofilms on substrates are universal and essential phenomena in nanoelectromechanical systems (NEMS). Van der Waals (vdWs) interactions play an important role in the dynamic behaviors of ...
Optimization of Sustainable Alkali Activated Municipal Solid Waste Incinerator Bottom Ash Materials with High Performance
Publisher: American Society of Civil Engineers
Abstract: In general, municipal solid waste incinerator bottom ash (IBA) is mainly utilized as fillers in nonstructural concrete products due to its low reactivity. In this study, the high-strength alkali-activated materials (AAMs) ...
