Mechanical behavior of a ceramic matrix composite material
… amount of damage within each specimen. Several nondestructive testing techniques, including acousto-ultrasonics (AU), were performed on the specimens periodically during testing. The AU signals were monitored through the use of an IBM compatible personal computer with a high speed data …

The effect of cracks on the dynamic behavior of bars and shafts
Nondestructive methods of detecting cracks in structural components and machinery are important, both in preventing failures and in establishing maintenance procedures. This thesis considers how the vibration behavior of cracked members can be modelled mathematically and how these mathematical …

The autecology of Stipa Trichotoma Nees (Nassella Tussock) on Rhodes Estate, in the South-Western Cape
… rate of tussocks in the field was studied using nondestructive methods while more accurate biomass experiments were undertaken on nursery grown plants. These experiments revealed that nassella tussock has a relatively low growth rate with maximum growth occurring in spring to early summer. The …

Localized Excitation Fluorescence Imaging (LEFI)
… limitation in tissue engineering is the lack of nondestructive methods to assess the development of tissue scaffolds undergoing preconditioning in bioreactors. Due to significant optical scattering in most scaffolding materials, current microscope-based imaging methods cannot "see" through thick …
