A Study of the Parameters Associated With Employing Laser Speckle Correlation Fringes to Measure In-Plane Strain
Abstract
Basic experimental parameters associated with using laser speckle correlation fringes to measure in-plane strain have been investigated. Equations and inequalities are derived which provide bounding numbers for many of the physical parameters. The feasibility of employing this technique for obtaining in-plane strain data in a microscopic region is shown. This suggests that it may be applicable for studying strain distributions in the vicinity of either a crack or an interference fit fastener.
