title: Time-average reflection-moiré method for vibration analysis of plates.
abstract: A moiré method is described whereby time-average slope contours are obtained from vibrating plates. It has an advantage over deflection contouring methods in that only first-order differentiation of experimental data is needed for stress calculations.
