Abstract: Strains in a flexed plate are directly related to the second derivatives of the plate deflections. A technique is developed which enables shearography to measure second derivatives of deflection ...

Abstract: This paper describes a new technique called “Holo-moiré interferometry” which combines the moiré and holographic techniques so that full-field measurement of the displacements normal to the line ...

Abstract: A novel treatment of computerized tomography is developed to calculate strains and displacements at internal nodes from known boundary displacements. The formulation is blended with finite element ...

Abstract: During holographic inspection of glass fiber reinforcesd plastic (GRP) laminated plates, perturbation in the fringe patterns not only reveals the presence of an unbond but also enables estimation ...
