Abstract: This paper examines the mechanisms of thin-walled tube cropping and the necessary equipment and tooling to minimize the cross-sectional distortion of billets. Tube cropping experiments identify ...

Abstract: In this paper a simple analysis of strip drawing, including the influence of back tension on drawing force, is developed and verified by experiments using new sapphire dies and traditional ...

Abstract: An upper-bound solution for the cropping of thin-walled tubes is developed, based on a plastic hinge approach, to predict the load-deflection behavior up to the point of shearing. A simple ...

Abstract: Interval analysis is a growing branch of computational mathematics where operations are carried out on intervals instead of real numbers. This paper presents the first application of this method ...

Abstract: A new analytical model is developed for the reduction of noise inside a cavity using distributed piezoelectric actuators. A modal coupling method is used to establish the governing equations ...
