Abstract: In the present investigation, the prolateness and the deformation of sheet metal deformed under lateral pressure with dies of different shoulder radii are analyzed. It is found that at the ...

Abstract: The displacements and strains of a circular specimen subjected to hydraulic pressure are studied and are compared with theoretical results predicted by previous investigators. By proposing a ...

Abstract: In this paper, the membrane stresses induced in axisymmetrical shells subjected to internal loading are analyzed in the light of curvatures. This approach enables a deeper understanding of the ...

Abstract: In this paper, a pattern is observed which relates the stress-strain curve of sheet materials to the shape and instability of hydroformed axisymmetrical thin shells. According to this pattern, ...

Abstract: In this investigation, two double-stage forming processes are used to study the effects of prestrain on sheet metal formability. The processes chosen are the bulge test and the plunger test ...

Abstract: Double-exposure holography has been shown to be a useful nondestructive testing technique for the detection of debonds in laminates when subjected to vacuum stressing. The size of a debond is ...

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: Circular plates, under unknown clamping conditions and containing simulated defects in the form of circular localized thinning or thickening, are inspected by double-exposure holography. With an ...

Abstract: The relationship between the geometry and the membrane stresses of a thin shell under internal or external pressure is analyzed through the concept of prolateness. Prolateness is a quantitative ...
