Characterization of barely visible impact damage (BVID) in polymer matrix composites (PMCs) is necessary to use slow crack growth damage tolerance models and evaluate remaining life of PMC components. Azimuthally scanned angled-beam pulse-echo ultras

Finite element (FE) modeling has been coupled with resonant ultrasound spectroscopy (RUS) for nondestructive evaluation (NDE) of high temperature damage induced by mechanical loading. Forward FE models predict mode-specific changes in resonance frequ

Polymer matrix composites (PMCs) are experiencing a growth in their use for civilian and military aircraft. However, the certification process for PMCs leads to new requirements for nondestructive evaluation/inspection (NDE/I). For example, in metall

Recent work has demonstrated the capability of applying inverse methods to automated eddy current (EC) data of surface breaking cracks and notches of various sizes, orientations and aspect ratios. However, not all eddy current indications in turbine

Characterization of delamination fields in 3D for impact-damaged composites is necessary to achieve the USAF objective of damage tolerance for polymer matrix composites. Oblique angle pulse echo ultrasound inspection has been hypothesized as a potent
