Paper Abstract

By using a "white-light" laser to illuminate a thin sheet of a transparent body seeded with tiny glass beads interior strain fields can be obtained by photographing the speckles before and after deformation via double exposure and subsequent Fourier filtering. Experimental results of interior strains of a block loaded by a ball were obtained and compared to theory with good agreement.
