Paper Abstract

Some recent applications of digital speckle photography in experimental mechanics are presented. Topics include the measurement of the in-plane deformation close to a triangular notch through an optical microscope, the 3D- deformation field of a sheet of paper subjected to increasing heat, the deformation of cardboard subjected to uniaxial stress, the shape of a curled sheet of paper, and the in-plane strain fields in an uniaxially stressed sheet of aluminium around a rectangular notch and a circular hole, respectively.
