Paper Abstract

An alternative to strain gauge technology is proposed using the adoption of a laser vibrometer to measure dynamic surface response. This data can then be applied to evaluate the bending strain in the structure. The simple theory is presented for beams and plates undergoing discrete frequency harmonic motion and random vibration. The sources of errors are analysed and a judgement on the method is given for future applications.
