Stability of Systems of Rigid Bodies by Bounding Theorems
The stability of systems of systems of rigid bodies subjected to conservative and dissipative forces is investigated by considering the minimization of a work function subject to the kinematic...
Finite Element Large Deflection Analysis of Cylindrical Shells with Different Types of Cutouts
Nonlinear finite element is used to find the elastic buckling load and the maximum deflection for cylindrical shells subjected to unsymmetrical pressures due to wind. These shells are...
Inflation Instability of Cylindrical Membranes
A new procedure which investigates inflation instability of cylindrical nonlinear membranes is developed. The general characteristics of inflation instability are described. An efficient...
Modal Analysis of Vibration Response for Condition Monitoring of Structures
The response of a structure to load is evidence of what the structure is; of the materials, members, connections and form of the structure. Response is evidence as well of the condition...
An Elasticity Solution for a Transversely Isotropic Material Containing a Spherical Shell Under Arbitrary Axisymmetric Loading
A three-dimensional elasticity solution is obtained for a transversely isotropic solid containing an isotropic spherical membrane shell. Perfect bonding is assumed between the shell and...
Influence of Gas Phase Turbulence on the Transport of Particles
An interesting and perhaps unexpected flow feature characterizing the transport of a gas-solid suspension in a vertical duct is the radial nonuniformity of particles over the tube cross-section....
Locally Buckled Plastic Hinge Behavior Under Monotonic and Cyclic Loading Condition
In order to clarify the influences of local buckling under monotonic and cyclic loading conditions, experimental studies were carried out on W8x10 A-36 structural steel members subjected...
Thermal Load for p-Version Laminated Elements
A p-version finite element formulation is presented for determining temperature stresses in laminated composite axisymmetric problems. Formulation for a rectangular axisymmetric p-version...
Stresses in Open Section Fiber Reinforced Composite Beams Under Constant Shear Loading
A strength of materials approach from the ply level is used to derive expressions for stresses in statically determinate open section composite beams subjected to constant shear loading....
Laboratory Testing of Mechanical Rock Bolts
An analytical solution to a boundary value problem of a clamped cylindrical panel with anti-symmetric angle-ply laminations subjected to transverse loads is presented. Sanders' kinematic...
Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...
Conceptual Design of Modules for a Lunar Base
This paper describes the development of cubically shaped aluminum modules which could be variously arranged to form living and working quarters for a lunar base. The module components...
Structural Characterization of an Articulated-Truss Joint
A first generation space crane articulated-truss joint was statically and dynamically characterized in a configuration which approximated an operational environment. The articulated-truss...
Mars Containers: Dust on Teflon Sealing Surfaces
As part of an evaluation of suitable hermetic seals for containers for Martian rock and soil samples, teflon (TFE) o-ring static face seals were challenged with silica gel, basalt, and...
Lunar Surface Mining Equipment Study
In response to the Space Exploration Initiative (SEI), a large number of lunar base scenarios have been proposed by various members of the research community. The National Aeronautics...
The Effect of Multiple Compliant Layers at the Fiber-Matrix Interface on Residual Thermal Stresses in Metal Matrix Composites
The large mismatch in thermoelastic properties of the fiber and matrix phases in advanced metal matrix composites, coupled with high consolidation temperatures, produces severe residual...
Shouldn't it be
A Traffic Impact Assessment is a single mode analytical tool that is used to evaluate new development proposals. Its use continues at a time when the transportation community is being...
Nowcast Protocol for the Great Lakes Forecasting System
The Great Lakes Forecasting System is a cooperative federal-university undertaking designed to implement a predictive system for each of the Great Lakes. The desired forecasts concentrate...
Modeling 3-D Circulation Using the DSS Technique
The direct stress solution (DSS) technique allows a numerical internal mode solution for the vertical variation of shear stress, rather than velocity, in a three-dimensional circulation...
Reliability Analysis of Uncertain Systems Under Random Loadings
This study considers the reliability assessment of uncertain systems under random loadings. The fast integration method (Wen and Chen, 1987) in conjunction with a second order asymptotic...
