Boston's Commuter Comeback
More than 30 years after its abandonment, the Old Colony Railroad in Massachusetts is being revived through a �480 million rehabilitation project to serve residents southeast of Boston....
Depressing Traffic Top-Down
Top down construction will permit the City and County of Denver to maintain traffic at two congested intersections while a tunnel is driven below them. The project, which will carry Speer...
Doubling A Pipeline
The 36 in. natural gas pipeline built 32 years ago by Pacific Gas and Electric (PG&E) its subsidiary Pacific Gas Transmission (PGT) from Canadian fields to central California has...
Human Extender: A Material Handling System
A human's ability to perform physical tasks is limited by physical strength, not by intelligence. `Extenders' are a class of robot manipulators worn by humans to augment human mechanical...
Developing Plans for Robotic Excavators
We would like a robot excavator that is able to excavate a volume of soil according to specification. To this end we have developed a general method that can be used to provide prescriptions...
Advancement of Material Handling Technologies for In-Place Asphalt Pavement Recycling
New technologies for asphalt pavement resurfacing are improving dramatically with the advancements being made to related equipment technologies. This paper focuses on the recent developments...
Demands and Satisfiers for Automation and Robotics in Construction: Differences Between Japan and the United States
The construction industries in Japan and the United States face problems of productivity, quality, safety, and skilled labor shortages. Automation and robotics are often proposed as solutions...
A Conceptual Study of A Solar Power Satellite Using Centrifugal Force
We studied the self deployable Solar Power Satellite (SPS) using centrifugal force in order to explore ways in reducing construction costs. We designed a 340 kW SPS, and studied the unfolding...
Modal Interaction in the Response of Laminates
A higher-order shear-deformation theory is used to analyze the interaction of two modes in the response of thick laminated rectangular plates to transverse harmonic loads. The case of...
Comparison of Donnell and Higher Order Nonlinear Models for Dynamically Loaded Composite Plates and Shells
The dynamic buckling behavior of composite cylindrical shells subjected to a transverse point load is considered. The behavior of undamped cylindrical shells of varying radii is analyzed...
Dynamics of Laminated Plates with Layer Waviness
Composite structures usually exhibit a high strength-to-weight ratio as compared to traditional structural materials. This makes them attractive solutions in many aerospace applications....
Nonlinear Analysis of Stiffened Laminated Cylindrical Shells Using the Layerwise Theory of Reddy
The layerwise shell theory of Reddy is used to develop the buckling and the postbuckling equations of circular cylindrical shells reinforced by means of axial and ring stiffeners and subject...
Large Deformation Theory Using Truncated Rotations
Today's aerospace industry has advanced to the point of using optimum design techniques in virtually all applications. In structural elements, orthotropic fiber composite materials have...
Analysis of Composite Panels Using Newton's Method
Postbuckling response prediction of composite panels using Newton's method will be discussed. The traditional approach of nonlinear finite element analysis is to use a Newton-Raphson approach...
Snap Buckling of a Delaminated Layer in a Composite Cylinder
We investigate snap buckling of a thin delaminated layer on the inner surface of a contracting thick cylinder. Finite-deflection solutions of the layer with or without considering the...
A Membrane Structure for a Lunar Assembly Building
This paper describes potential design options and construction approaches for the development of an inflatable membrane structure of non-circular cross section. This structure could be...
Analysis of Inflating Habitable Space Structures with neomass (near-Earth-object mass)
The discovery of near Earth objects (NEOs), during August 1992, and that one of them is a dormant comet, dramatically changed the potential availability of near-Earth resources. NEOs provide...
Axisymmetric Vibrations of Thick-Walled Cylindrical Tubes in the Presence of Thermal Residual Stresses
The paper presents an approach to the analysis of axisymmetric vibrations of thick-walled specially orthotropic multilayered cylindrical tubes. The first part of the paper is concerned...
Inelastic Response of Metal Matrix Composite Tubes
An analytical method which exactly satisfies the equations of the boundary value problem for the inelastic response of laminated metal matrix composite tubes on a point-wise basis is presented....
