RISStiffness-Matrix Formulation of Beams with Shear Effect on Elastic Foundation
Publisher: American Society of Civil Engineers
Abstract: A stiffness matrix for a beam element with shear effect on an elastic foundation is developed using the differential-equation approach for plane-frame analysis. Small-displacement theory and linear-elastic material are ...
Design Methodology for Biomimetic Propulsion of Miniature Swimming Robots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Miniature and energy-efficient propulsion systems hold the key to maturing the technology of swimming microrobots. In this paper, two new methods of propulsion inspired by the motility mechanism ...
Implicit Multigrid Computations of Buoyant Drops Through Sinusoidal Constrictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-dimensional computations of dispersed multiphase flows involving complex geometries are presented. The numerical algorithm is based on the front-tracking method in which one set of governing ...
Kinematic Properties of Tripode (Tri-pot) Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The geometry of tripode (also called tri-pot) joints or shaft couplings is simplified by folding one side onto the other, and the kinematic properties are obtained. Due to a built-in orbital ...
Assessment of Improved Nonlinear Static Procedures in FEMA-440
Publisher: American Society of Civil Engineers
Abstract: Nonlinear static procedures (NSPs) presented in the FEMA-440 document are evaluated for nondegrading three- to nine-story reinforced concrete moment-resisting frame systems. Evaluations are based on peak single-degree-of-freedom ...
Method for Modeling Lane-Based Driving Discipline of Drivers on Divided Multilane Urban Roads
Publisher: ASCE
Abstract: Lane-based driving (lane-keeping) problems generally prevail in undeveloped and developing countries, where drivers’ lane-keeping behaviors are fairly weak for reasons such as poor surface conditions, undisciplined driving, ...
Similarity Criteria for Modeling Mixed-Convection Heat Transfer in Ducted Flows of Supercritical Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A key subject of interest for technologies that involve flows of fluids at the supercritical thermodynamic state is the development of prediction methods that capture the fluid dynamics and convection heat transfer at this ...
Passive Manipulation of Separation-Bubble Transition Using Surface Modifications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Through experiments using two-dimensional particle-image velocimetry (PIV), this paper examines the nature of transition in a separation bubble and manipulations of the resultant breakdown to ...
Transition Mechanisms in Separation Bubbles Under Low- and Elevated-Freestream Turbulence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Through numerical simulations, this paper examines the nature of instability mechanisms leading to transition in separation bubbles. The results of two direct numerical simulations are presented ...
Numerical Study of Instability Mechanisms Leading to Transition in Separation Bubbles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, transition in a separation bubble is examined through numerical simulation. The flow Reynolds number and streamwise pressure distribution are typical of the conditions encountered ...
