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....

Mechanics of Curved Fiber Bundles in Composites
Fiber undulations are inherent to manufacturing processes like braiding and filament-winding, and sometimes occur as defects in other composite structures. This paper summarizes the status...

Behavior of Bolted Joints in 3-D Braided Composites
As composites are used more as replacements for metals in space structures, the question arises as to the most efficient way to join the components. Mechanical fasteners are a common joining...

Damage Tolerance of Thin Composite Reinforced Membrane Structures
Structural performance of fiber reinforced flexible composite membranes, designed as pressurized shelters for space exploration, is investigated via computational simulation. An integrated...

Hygrothermal Effects in Composite Sandwich Panels
The macromechanical analysis of a composite panel with laminate facings and a honeycomb core is carried out by taking into account mechanical and hygrothermal loads. In this analysis the...

Spacecraft Wall Design for Orbital Debris Impact
This paper describes a method for obtaining the optimal rise angle of corrugated bumpers for the design of space structures in the event of an on-orbit impact. The procedure determines...

Distributional Information for Ejection Fragments
Due to lack of experience of building structures on the lunar surface and the variability that will exist in the loading as well as the structural resistance, it is suggested that initial...

Erectable Truss Hardware for Large Space Structures
The KATLOK connector is a truss structure connector that was designed to be compatible with manual assembly by an astronaut in an extra-vehicular activity (EVA) suit, telerobotic assembly...

Construction Operations on the OUTPOST Platform in Orbit
GLOBAL OUTPOST, Inc., with significant NASA assistance, proposes to place an External Tank (ET) of the space shuttle in orbit for commercial purposes. The OUTPOST Platform is designed...

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...

Adaptive Space Station Technologies and Systems for a Lunar Surface Return Mission
The current global economic climate, in particular that of the United States, has impacted all aspects of government spending. Wise use of existing, as well as near-term planned, assets...

A Space Station Simulation: EXEMSI '92 A Study on Confinement and Isolation of a Mixed Crew of Four during 60 Days
Manned spaceflight is entering a new era. The next period will be characterized by long duration stays in space and heterogenous crews. EXEMSI '92 was an attempt to study the human-related...

Methods to Mitigate Thermally Induced Distortion
The purpose of this paper is to show the magnitude of bending on the Space Station Freedom Navigation Base as induced by thermal expansion and contraction over the operating range -45...

Global Environmental Change: Geoengineering Technology
The `overview effect,' looking at the entire Planet Earth from space, has communicated the reality of the limited extent of our environment and its apparent fragility. Space continues...

Update of the Implications of Recent Space Resource Discovery
Immense resources have been discovered in the space near Earth during the last decade. Last August, 1992, one of the resource objects was discovered to contain a key ingredient that might...

A Summary of the NEPSTP Nuclear Safety Program
The Nuclear Electric Propulsion Space Test Program (NEPSTP) is sponsored by the Ballistic Missile Defense Organization (BMDO) to demonstrate and evaluate the Russian-built TOPAZ II nuclear...

Mars Terraformation Revisited
This report is a look into the future; not only that of the solar system, but of humans. With the goal of changing Mars into a living planet, we also have to face the change of the human...

Is It Possible to Colonize Mars?
Is it possible to colonize the planet Mars? A planet that is believed to be the most clement planet in the solar system, next to Earth. Despite the fact that it is a very clement planet,...

Construction of a Lunar Base
The United States' space program has the capabilities to build a lunar base, but must build an infrastructure which allows the easy transportation of the construction materials. Once this...

Biosphere II - Its Effects on Space Colonization
In the middle of the Arizona desert, a strange sight can be seen. A small world with ecosystems and different climate zones, just like Earth, is enclosed in glass and steel. The 3.15 acre...
