Calculation of wind borne debris impact in tornado event
… is caused to buildings due to wind-borne debris, which are usually damaged structural members and components with insufficient attachment. This debris, also referred to as missiles, can penetrate building walls and roofs and jeopardize human life. Because of this, there are standard impact …

Analysis of laminated architectural glazing subjected to combined wind and debris impact loading
… glazing against combined wind and windborne debris impact. Here both small-hard (like roof gravel) and large-soft (like timber) windborne debris are considered. The stress response of the rectangular laminated architectural glazing was modeled using the finite element code ABAQUS. The effect …

Design, Fabrication, and Testing of an EMR Based Orbital Debris Impact Testing Platform
<p>This paper describes the changes made from Cal Poly’s initial railgun system, the Mk. 1 railgun, to the Mk. 1.1 system, as well as the design, fabrication, and testing of a newer and larger Mk. 2 railgun system. The Mk. 1.1 system is developed as a more efficient alteration of the original Mk. 1 …

Wind-Borne Debris Resistance of Façades: Identification of Alternative Impact Test Requirements
… hospital, most of the windows were broken by the impact of wind-borne debris. The structure of the hospital has remained intact and only one section of the building was not affected by façade breakage: the Behavioral Health Unit, a result that was ensured by breakage-resistant windows. To avoid …

Graphene Nano-Composites For Hypervelocity Impact Applications
… cluttered with natural meteoroids and man-made debris, which can travel at velocities approaching 15 km/s. Most space activities within the LEO will encounter this environment. Thus, the spacecraft and its hardware must be designed to survive debris impact. This research introduces new …

Numerical Investigation of Tsunami-Borne Debris Interaction with Coastal Bridges
… vulnerable to damage from tsunami-driven debris, such as boats, vehicles, and shipping containers, which upon impact can remove a bridge superstructure from its supports. The significance of understanding the effect of floating debris on coastal bridges cannot be overemphasized, as …

Retrofitting unreinforced concrete masonry to resist tornado loading
… against both out-of-plane flexural loads and debris impact, and attempts to determine if enough strength can be added for such wall assemblies to meet the requirements of a Tornado Safe Room as dictated by FEMA. By adapting current design guidelines and extrapolating evidence on the …

Dynamics and Control of a Pressurized Optical Membranes
… Among those encountered are thermal radiation, debris impact, and slewing maneuvers. Thus, dynamic control is essential for the adequate performance of thin-film membrane mirrors. With this in mind, the work described herein aims to improve the performance of optical membranes with an …

In Space Reverse Logistics
… design for mitigating and remediating space debris in proliferated Low Earth Orbit (pLEO) constellations. The ISRL design aims to collect defunct satellites from their operating orbits and to bring them to a Workshop Space Station (WSS) for centralized on-orbit servicing (OOS). A modular …

The Structural Response of a Frame-Membrane Lunar Habitat Subjected to Impact and Thermal Loads
… structural support for any harsh loading such as impact, blast, or heavy wind loads. Because of their success on Earth, frame-membrane structures have also been proposed as possible lunar habitat. However, for any proposed lunar habitat, including frame-membrane structures, to be successful, it …

Evolution of artificial space debris clouds
… whether by explosion or collision, a cloud of debris is formed. The overall objective of the PhD is to examine the interaction between the debris clouds produced by on-orbit fragmentation events and specific space systems. A breakup event will give rise to concentrations of debris which, for …

Parametric Soil-Structure Modeling for Rapid Climatic Disaster Response
… climate changes have seemly caused acerbating impacts on coastal environments in terms of severe meteorological hazards, such as hurricanes and their induced storm surges, flooding, and heavy precipitation. Recent disasters of these types, such as HurricaneSandy, have afflicted millions in …
