RISGlobal Tangent Visibility Analysis for Polyhedral Computer Aided Design Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Visibility analysis is broadly used in milling and casting process planning and in coordinate measuring machine applications. However, standard visibility analysis (which involves determining ...
Setup Planning Automation for Six-Axis Wire Electrical Discharge Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A modern six-axis wire electrical discharge machining (WEDM) system is capable of producing more complex geometries than 2D, 2½D, or ruled surface parts. The rotational axis on a six-axis ...
Factors Influencing the Spatial Differentiation of Water Yield: Statistics and Appraisals with Predictors of Subbasins
Publisher: American Society of Civil Engineers
Abstract: Water yield in a watershed is mainly affected by both climatic and physiographical factors, but the interaction between different factors still cannot be completely understood. The soil and water assessment tool (SWAT), ...
Flow in Sewers with Bottom Obstacles
Publisher: ASCE
Abstract: This study conducted experiments to investigate the impact of bottom obstacles, specifically broad-crest weir-type and cylindrical obstacles, on the flow within a sewer pipe. It was observed that these two types of obstacles, ...
Dynamic Demand of Bridge Structure Subjected to Vessel Impact Using Simplified Interaction Model
Publisher: American Society of Civil Engineers
Abstract: Assessing the dynamic demand using general-purpose finite-element codes is not only low in efficiency, but also unaccepted in practical application due to the complicated nonlinear dynamical behaviors of vessel-bridge ...
Comparative Field Tests on Straight-Sided and Belled Piers on Sloping Ground under Combined Uplift and Lateral Loads
Publisher: American Society of Civil Engineers
Abstract: Comparative field tests were carried out on two straight-sided piers and two belled piers under combined uplift and lateral loads on arid loess sloping ground with an inclination angle of 20°. The pier-head uplift and ...
Sulfide Generation in Force Mains and Its Control Using Nitrate Dosing
Publisher: ASCE
Abstract: Sulfide generation rates in the force mains of four pump stations in Edmonton, Alberta, Canada, were evaluated in the field, and a continuous nitrate dosing was applied in the pump wet well of the Big Lake pump station to ...
Flutter Mechanism of Timoshenko Beams in Supersonic Flow
Publisher: American Society of Civil Engineers
Abstract: The flutter mechanism for cantilevered beam in supersonic flow is studied based on Timoshenko beam model and piston theory. The partial differential equations governing transverse deflection and rotation angle of the beam ...

Progressive Collapse of Flat Plate Substructures Initiated by Upward and Downward Punching Shear Failures of Interior Slab–Column Joints
Publisher: ASCE
Abstract: A slab-column joint in a flat plate structure may exhibit upward or downward punching shear (UPS and DPS) failure when subjected to different abnormal loading conditions. This can cause distinct residual deformations of ...
