Exploring the Impact of Car-Following Models and Controller Formulations on Autonomous Vehicle Motion Planning
Publisher: American Society of Civil Engineers
Abstract: AbstractEffectively planning the behavior of autonomous vehicles (AVs) while accounting for
their mechanical properties and traffic flow characteristics is a challenging task.
This study evaluates different car-following ...
Analysis of Material Nonlinear Problems Using Pseudo-Elastic Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method based on linear elastic finite element analysis is presented for stress field determination of elasto-plastic problems. Hencky’s total deformation theory is used to define effective ...
On Shallow Shells of Transversely Isotropic Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an improved shell theory for the analysis of shallow shells of composite materials such as pyrolytic graphite, that exhibit certain unusual and complex thermal properties. ...
Simplifying the Development and Usage of Fixtures for Sheet Metal and Composite Aircraft Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on a survey of small- to medium-sized companies that supply sheet metal parts to the major aircraft manufacturers, there is a need for a more simplified, flexible and inexpensive method ...
Travel Modeling with and without Feedback to Trip Distribution
Publisher: American Society of Civil Engineers
Abstract: Many regional agencies model travel demand without feeding assigned travel times back to the trip distribution step. This method saves time and money but is likely to be biased in favor of build alternatives because it ...
Discussion: Cable-Stayed Bridge Concept for Longer Spans
Publisher: American Society of Civil Engineers
Finite Element Based Member Stiffness Evaluation of Axisymmetric Bolted Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For a reliable design of bolted joints, it is necessary to evaluate the actual fraction of the external load transmitted through the bolt. The stiffness of the bolt and the member of the ...
Systems‐Level Evaluation of Automated Urban Freeways
Publisher: American Society of Civil Engineers
Abstract: The automation of urban freeways is a major feature of the new surface transportation act. Reducing freeway congestion can be presumed to have drawbacks, however, in terms of induced travel and possibly greater travel costs ...
Free Vibration Behavior of Prestressed Beams
Publisher: American Society of Civil Engineers
Abstract: A Rayleigh-Ritz free vibration analysis of a simply supported beam is carried out in this note with prestress effects included through an axial compressive load and with shear deformation and rotatory inertia considered. ...
Stress-Intensity Factors for Internal and External Surface Cracks in Cylindrical Vessels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this paper is to present stress-intensity factor influence coefficients for a wide range of semi-elliptical surface cracks on the inside or outside of a cylinder. The crack ...
