Dynamic Analysis of a High Speed Transport Model by Using a Piecewise Continuous Timoshenko Beam Model

*Conventional treatment of structural dynamic analysis and control is based on the finite element structural model. But such a treatment uses a very large number of elements which is usually...*

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...*

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....*

Thermal Cycling of Thin and Thick Ply Composites

*An experimental study was conducted to determine the effects of ply thickness in composite laminates on thermally induced cracking and changes in the coefficient of thermal expansion (CTE)....*

Convergence Rates of the Method of Successive Elastic Solutions in Thermoplastic Problems of a Layered Concentric Cylinder

*This paper examines convergence rates of the method of successive elastic solutions, proposed by Mendelson, in determining the thermoplastic response of an arbitrarily layered concentric...*

Space Station Microgravity Analysis and Assessment

*The space station will be a platform for microgravity research. For superior microgravity science, the experiment locations must experience very little acceleration in the quasi-steady...*

Modeling of Interaction of Small Particulates in Earth Orbit

*The hazards posed by small debris is an area of increasing concern for all space systems. Depending on the size and relative encounter velocity of small particulates, there are a variety...*

Integrated Spacecraft Environments Model (ISEM)

*Capabilities of the ISEM code are presented that can aid in the understanding of the complex interactions between a space system and the ambient environment. The development of ISEM has...*

Helium-3 on the Moon: Model Assumptions and Abundances

*Solar-wind particles are present in the outer few 100 angstroms of each soil particle of the Moon. Of particular interest, are the volatiles hydrogen (40-100 ppm) and helium (5-45 ppm)....*

Hurricane Windspeeds at Inland Locations

*A critical review of the windfield and filling models used in the hurricane simulation procedure of Batts et al. [1980] clearly indicates that the hurricane windspeeds they obtained for...*

Modelling of Extended Endplate Bolted Connections

*A methodology based on finite element modelling is examined to study the behaviour of extended endplate bolted connections. ANSYS (Rev. 4.4), a large scale finite element program is used...*

An Overview of Shotcrete Usage on the SSC

*Shotcrete has been widely used on the Superconducting Super Collider for initial support of tunnel excavations in both the strong and weak rock formations encountered. Different types...*

Effects of Sea Surface Movement on Offshore Structures

*Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...*

A Generalized Approach to the Local Stability of Stiffened Plates: Part I–Mathematical Formulation

*The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...*

Dynamic Analysis of Unstable Structural Systems With Prescribed Velocities

*Structural systems that have large inextentional deformation, or in other words, deformation without stain are called 'Unstable Structural Systems.' They include cable structures, membrane...*

Optimal Design Conception of Grid Domes in Practice

*In this paper, the optimal design conception of grid domes in practice is presented. The classical dome shell structures covering some irregular boundaries often seems not to be satisfied...*

Explorations in Geodesic Forms

*Geodesic forms constitute an important family of structural systems. The objective of the paper is to show how the concepts of a mathematical tool called formex algebra and its programming...*
