dc.description.abstractThis paper presents a laser speckle technique and a computer based image processing system for strain measurement in plastics. A new correlation parameter, the Integrated Peak Spectral Intensity Coefficient H1 is proposed. Test results on polypropylene specimens subjected to uni-axial stretching show a correlation between the Integrated Peak Spectral Intensity Coefficient H1 and strain. The advantages of this method are its non-contacting nature, absence of gauge marks, no limitation on specimen design and it enables measurement of plastic strains of up to 40%. © 1995.
