Nondestructive Structural Damage Detection in Flexible Space Structures Using Vibration Characterization [PDF]
, 1991 Spacecraft are susceptible to structural damage over their operating life from impact, environmental loads, and fatigue. Structural damage that is not detected and not corrected may potentially cause more damage and eventually catastrophic structural ...

Damage Detection of Structural Systems with Noisy Incomplete Input and Response Measurements [PDF]
, 2002 A probabilistic approach for damage detection is presented using noisy incomplete input and response measurements that is an extension of a Bayesian system identification approach developed by the authors. This situation may be encountered, for example,

A Protection And Detection Surface (PADS) for damage tolerance [PDF]
A protection and detection surface (PADS) concept was studied for application to composite primary aircraft structures. A Kevlar-epoxy woven face sheet with a Rohacell foam core was found to be the most effective PADS configuration among the ...

Estimation of Delamination Crack Depth Using Passive Thermography [PDF]
Passive thermography is used to monitor small increases in temperature resulting from delamination damage formation in a composite hat-stiffened panel during quasi-static loading. The heating is composed of two heat generation components.

On-orbit damage detection and health monitoring of large space trusses: Status and critical issues [PDF]
The long lifetimes, delicate nature and stringent pointing requirements of large space structures such as Space Station Freedom and geostationary Earth sciences platforms might require that these spacecraft be monitored periodically for possible damage ...
