RISModel for a Sphere–Flat Elastic–Plastic Adhesion Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a cubic model for the sphere–flat elastic–plastic contact without adhesion. In the cubic model, the applied load and the contact area are described by the cubic polynomial functions of the displacement ...
Design Patterns of Soft Products Using Surface Flattening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a pattern development method for soft product design. We utilize a surface fattening method based on a mass-spring model to create 2D patterns unfolding from a three-dimensional (3D) model. ...
Wake Vortices and Boundary Layer Interaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The interaction between wake vortices from an upstream body and a downstream boundary layer is significant for both fundamental and practical aspects of fluid mechanics. An in-depth understanding of the underlying ...
Study on the Unplugging Technology Through Electric Explosion Controllable Shock Wave
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the increasing well plugging in oilfield development, a new unplugging technology is presented in this paper for the downhole plugging by using high voltage pulse wave. Based on the mechanism analysis, the circuit ...
Electrostatically Driven Creep in Viscoelastic Dielectric Elastomers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We utilize a nonlinear, dynamic finite element model coupled with a finite deformation viscoelastic constitutive law to study the inhomogeneous deformation and instabilities resulting from the application of a constant ...
Experimental Study on Tornado-Induced Wind Pressures on a Cubic Building with Openings
Publisher: American Society of Civil Engineers
Abstract: Wind pressures acting on a cubic building with openings exposed to stationary tornadolike vortices were studied experimentally. The effects of opening ratio, single central opening azimuth, and radial distance between the ...
Optimization of Rotary Axial Percussion Drilling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Rotary axial percussion drilling is a high-speed drilling technology that has been widely applied. However, the traditional single-impactor arrangement has low drilling efficiency, is prone to intensify drillstring ...
Scalable and Accurate Crack Segmentation for Infrastructure Health Monitoring Using EfficientNetB0 and a Context-Aware Attention Mechanism
Publisher: American Society of Civil Engineers
Abstract: AbstractIn response to the growing need for accurate and automated infrastructure assessment,
this study introduces a novel crack segmentation framework that combines an EfficientNetB0
encoder with an enhanced U-Net decoder ...
Estimation of Uncertainty in Temperature Observations Made at Meteorological Stations Using a Probabilistic Spatiotemporal Approach
Publisher: American Meteorological Society
Abstract: probabilistic spatiotemporal approach based on a spatial regression test (SRT-PS) is proposed for the quality control of climate data. It provides a quantitative probability that represents the uncertainty in each temperature ...
Development of a High Pressure, High Temperature, Optically Accessible Continuous Flow Vessel for Fuel Injection Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A vessel has been designed for nonreacting fuelinjection experiments with continuous flow of sweep gas at pressures up to 1380 kPa and temperatures up to 200 آ°C. Four orthogonal windows provide optical access for ...
