RISStudy of Deformation Mechanism and Surface Formation of Laser Coupled Ultrasonic Vibration-Assisted Turning of SiCp/Al Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to enhance the machinability of SiCp/Al composites and improve the surface quality after machining, a laser-ultrasonic vibration-assisted machining (LA-UVAM) method is presented. In order to investigate the ...
Vineyard energy partitioning between canopy and soil surface: dynamics and biophysical controls
Publisher: American Meteorological Society
Abstract: or sparse planting crops, soil surface plays an important role in energy balances processes within the soil-canopy-atmosphere continuum, thus it?s necessary to partition field energy fluxes into soil surface and canopy, ...
Research on Deformation Mechanism of Cutting Nickel-Based Superalloy Inconel718 Based on Strain Gradient Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The traditional material constitutive model can effectively simulate the mechanical properties during the cutting process. However, the scale characteristics contained in materials are not considered in the traditional ...
Research on Strengthening Mechanism of Rare Earth Cemented Carbide Tool Material
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the first principle method based on density functional theory is adopted to establish the interface model of WC/WC-Co through the software Materials Studio (MS). On the basis of this interface structure, ...
Physically Based Constitutive Model for Viscoplastic Deformation of Inconel718 at High Strain Rates and Temperatures
Publisher: ASCE
Abstract: In the cutting process of nickel-based superalloys, because of the high strain rate and cutting temperature, the cutting deformation is complex and there exist hardening and softening phenomena. Therefore, the present study ...
Data-Driven Prediction of Coefficient of Friction in Wet Friction Components: A Model Development and Interpretability Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Predicting the coefficient of friction (COF) is essential for enhancing the efficiency and reliability of mechanical systems. Nevertheless, traditional mechanistic models relying on fixed values or fitted curves fail to ...
Seasonal Variations of Yellow Sea Fog: Observations and Mechanisms
Publisher: American Meteorological Society
Abstract: Sea fog is frequently observed over the Yellow Sea, with an average of 50 fog days on the Chinese coast during April?July. The Yellow Sea fog season is characterized by an abrupt onset in April in the southern coast of ...
A Probabilistic Evaluation Method on Temperature and Time-Dependent Stress Intensity Limit St in Creep Assessment of Components at Elevated Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Creep is an important damage mode of components at elevated temperatures, and the temperature and time-dependent stress intensity limit St is an essential indicator in creep assessment of components. In general, the safety ...
