Comparison of Optical Coherence Tomography, X-Ray Computed Tomography, and Confocal Microscopy Results From an Impact Damaged Epoxy/E-Glass Composite

January 1, 2002
Author(s)
Joy Dunkers, D P. Sanders, Donald L. Hunston, M J. Everett, William H. Green
Optical coherence tomography (OCT) is an emerging technique for imaging of synthetic materials. OCT is attractive because of the combination of its high sensitivity (>90 dB), high resolution ((10-20) mm), and low cost ($75 k). The value of any new

Control of Intrinsic Instability of Superelastic Deformation

January 1, 2002
Author(s)
Julia Slutsker, Alexander L. Roytburd
The superelastic deformation of shape memory alloys has intrinsic instability as a result of incompatibility between martensite and austenite phases at stress-induced transformation. The instability leads to the stress-strain hysteresis of the superelastic

Crack Growth in Sapphire

January 1, 2002
Author(s)
Sheldon M. Wiederhorn, Ralph Krause
Crack growth was studied in sapphire on both the m-plane and the r-plane (rhombohedral twin plane). Crack growth on the m-plane fit a power law function of stress intensity factor and an Arrhenius function of temperature. Crack growth on r-plane double
