Abstract: While defects in laminated plates are readily revealed using double-exposure shearography and holography, when an incremental vacuum pressure is applied between the exposures, the apparent defect ...

Abstract: During hydroforming of sheet materials into axisymmetrical shells, varying the blank holding load causes a change in the draw-in condition of the flange, and hence deformation. By assuming the ...

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 ...

Abstract: Shearography is a double-exposure optical method which reveals defects in components from anomalies in interferometric fringe patterns. In this paper, disbonds of known shapes and sizes are ...

Abstract: In this investigation, the clamped portion of copper test specimens is allowed to be drawn slightly into the die throat when hydroformed into axisymmetrical shells. Changing the blank holding ...
