Abstract: Surfaces of many engineering structures, especially those of ships and airplanes, are commonly fabricated as either single- or double-curved surfaces to meet functional requirements. The first ...

Abstract: Line heating (LH) is a method of forming curved thick plates. Residual deformation of a steel plate is obtained by applying heat to the plate. Heat transfer analysis between a torch and the ...

Abstract: This paper proposes and develops a kinematics-based, systematic approach to determine the region of a plate to be rolled, in order to fabricate smoothly curved plates. The approach includes a ...

Abstract: The mechanics of die-less asymmetric rolling has been investigated in depth, for the first time, using a two-dimensional analytical model and a three-dimensional finite element model. In doing ...

Abstract: Thermal forming is a method to form a curved plate by inducing local shrinkage and angular distortion through heating and cooling. In this approach, two different methods are available: line ...

Abstract: In this paper, a localization method is proposed for improving the curved plate fabrication process. In the curved plate forming, checking the similarity of a manufactured plate to a CAD model ...

Abstract: A general and efficient methodology has been developed to analyze dimensional variations of a welded assembly, taking into account of weld distortion. Weld distortion is generally probabilistic ...
