RISEnhancing Wear Resistance of Selective Laser Melted Parts: Influence of Energy Density
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Selective laser melting (SLM) is a rapidly developing metal additive manufacturing technology. SLM process parameters have a direct impact on the microstructure of parts, which further affect wear behaviors. Increasing the ...
Investigating the Potential of Using Radar Echo Reflectivity to Nowcast Cloud-to-Ground Lightning Initiation over Southern Ontario
Publisher: American Meteorological Society
Abstract: The potential for using radar echo reflectivity to forecast cloud-to-ground (CG) lightning initiation in the 0?1-h time frame was investigated in southern Ontario, Canada. The main purpose of this investigation was to ...
Design and Simulation of Pressure Coordinated Control System for Hybrid Vehicle Regenerative Braking System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to solve the limitations and complexity of a pressure coordinated control system for hybrid regenerative braking, a new pressure coordinated control system applicable for a regenerative braking system of hybrid ...
A Displacement Equivalence-Based Damage Model for Brittle Materials—Part I: Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a displacement equivalence-based damage model for brittle materials is proposed. A new damage deactivation criterion, which depends on both the stress and strain states of the materials, is adopted. Based ...
A Displacement Equivalence-Based Damage Model for Brittle Materials—Part II: Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on the application of the damage model for brittle materials proposed in the preceding paper on theory. The evolution rule of damage derived using the Onsager relations is specified according to the ...
Parametric Identification of Nonlinear Vibration Systems Via Polynomial Chirplet Transform
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The response of a nonlinear oscillator is characterized by its instantaneous amplitude (IA) and instantaneous frequency (IF) features, which can be significantly affected by the physical properties of the system. Accordingly, ...
Short-Term Hydraulic Conductivity and Consolidation Properties of Soil-Bentonite Backfills Exposed to CCR-Impacted Groundwater
Publisher: American Society of Civil Engineers
Abstract: The present study investigated the effectiveness of two soil-bentonite slurry wall backfills, specifically sand/conventional Na-bentonite (NaB) and sand/hexametaphosphate (SHMP)-amended Ca-bentonite (SHMP-CaB), for the ...
Demand-Driven Spatiotemporal Variations of Flow Hydraulics and Water Age by Comparative Modeling Analysis of Distribution Network
Publisher: American Society of Civil Engineers
Abstract: Distribution network modeling is proposed to investigate and manage water quality variations in a distribution network. Common practice in the modeling relies on pipe network simplification through skeletonization and uses ...
Continental Slope Flow Northeast of Taiwan
Publisher: American Meteorological Society
Abstract: Hydrographic observations and current measurements with a Shipboard Acoustic Doppler Current Profiler over the continental shelf?slope junction northeast of Taiwan during 10?17 August 1994 allow the construction of the ...
CHANGES OF ATMOSPHERIC COMPOSITION AND OPTICAL PROPERTIES OVER BEIJING—2008 Olympic Monitoring Campaign
Publisher: American Meteorological Society
Abstract: Before and during the 2008 Beijing Olympics from June to September, ground-based and satellite monitoring were carried out over Beijing and its vicinity (BIV) in a campaign to quantify the outcomes of various emission ...
