“…To provide additional confirmation of the simulation validity, XY shear strain profiles at 2.54 cm from the impact point and the associated contact force profiles were simulated for the impact. The simulation results for all types of profiles were consistent with the experimental measurements in structure and amplitude [27]. These X and Y strain profiles were used to train and test a neural network approach to classifying the type and extent of damage.…”

“…They can learn to process data one way, and when conditions change, the processing can adapt to new conditions. ANN applications for delamination detection in composite structures, including damage assessment and fatigue monitoring, have been extensively studied [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Neural networks have been coupled with advanced sensing technologies to predict and generalize unknown parameters in physical systems.…”

“…Host materials include concrete, 29 metals, and composites, 27,30 and applications include the associated civil, aerospace, and automotive structures. [20][21][22][31][32][33] In particular, EFPI strain sensors have high dynamic and static sensitivity, a low physical profile, [12][13][14] and good compatibility with fiberglass reinforced plastic ͑FRP͒ composites. 30,34 However, EFPI suffers from nonlinearity, requiring extra processing.…”

“…[6][7][8]12 Strain sensing techniques are shown to be capable of characterizing impact-induced damage, warning of impending weakness in structural integrity, and assessing performance of composite structures. [20][21][22] For modal testing of structures, fiber optic sensors and ANNs have been combined to locate and classify damage from changes in resonant frequencies. 23 A Fourier series neural network ͑FSNN͒ has been employed in obtaining modal frequencies from the fiber optic sensor output.…”
