Abstract

This paper presents an investigation into the accuracy of 1D scanning laser Doppler vibrometry in measuring quasi-static surface strain of an aluminium beam specimen, induced by bending. The formulation and experimental setup of the strain measurement technique utilised in this research is presented, as well as the approach used to evaluate the accuracy of the technique. Finally, the affect various parameters have on the accuracy of the technique is presented, including the parameters of the numerical method, spatial interval between measurement points and amplitude of loading.
