RISData-Driven Telecommunication Outage Prediction during Hurricane Events
Publisher: American Society of Civil Engineers
Abstract: Telecommunication infrastructure (TI) has become an indispensable part in modern society, and its functionality is especially vital to emergency response during hurricanes. This study bridges the gap of lack of quantitative ...
BEM Treatment of Body Forces in Plane Orthotropic Elastostatics
Publisher: American Society of Civil Engineers
Abstract: A new boundary-element formulation is given in this paper to treat gravitational and centrifugal body forces in plane orthotropic media. In this method, two functions have been defined to satisfy the orthotropic potential ...
Design and Kinematic Analysis of a Novel Deployable Antenna Mechanism for Synthetic Aperture Radar Satellites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel deployable antenna mechanism for synthetic aperture radar (SAR) satellites. First, the topological structure of the new deployable mechanism is designed based on the five conditions expected to ...
Analysis and Numerical Evaluation of H∞ and H2 Optimal Design Schemes for an Electromagnetic Shunt Damper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The electromagnetic coupling effect can generate electromagnetic damping to suppress disturbance, which can be utilized for vibration serviceability control in civil engineering structures. An electrodynamic actuator is ...
A New Family of Deployable Mechanisms Derived From Two-Layer and Two-Loop Spatial Linkages With Five Revolute Pair Coupling Chains
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper aims to construct a novel family of deployable mechanisms from a class of two-layer and two-loop spatial linkages, each of which consists of an eight revolute pair (8R) single-loop linkage connected by a 5R ...
Dynamics Model Validation Using Time-Domain Metrics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Validation of dynamics model prediction is challenging due to the involvement of various sources of uncertainty and variations among validation experiments and over time. This paper investigates quantitative approaches for ...
A Method for Compliance Modeling of Five Degree-of-Freedom Overconstrained Parallel Robotic Mechanisms With 3T2R Output Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an approach to compliance modeling of three-translation and two-rotation (3T2R) overconstrained parallel manipulators, especially for those with multilink and multijoint limbs. The expressions of applied ...
Mechanics Design for Buckling of Thin Ribbons on an Elastomeric Substrate Without Material Failure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ribbons selectively bonded to a prestrained elastomeric substrate may buckle into three-dimensional (3D) microstructures after the prestrain release, leading to three possible deformation modes, global, local, and no ...
New Calculating Approach for the Ultimate Bearing Capacity of a Shallow Foundation
Publisher: ASCE
Abstract: The conventional method for calculating the bearing capacity is the method derived by Terzaghi, in which the embedment is simulated as a surface surcharge. The total bearing capacity is determined with two different failure ...
Three-Dimensional Thermal Stress Distribution of Opposed Firing Boiler: Numerical Study and Experimental Verification
Publisher: ASCE
Abstract: By coupling fluid dynamics and solid mechanics, a numerical framework has been developed to investigate the temperature distribution and stress field on the boiler walls and to propose useful advice on reducing the thermal ...
