Abstract: The collapse of thin cylindrical pipes subject to combined bending moment and external pressure has been studied. Nonlinear finite deflection thin shell theory is employed in the elastic solution. ...

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: 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: 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 ...
