AN ANALYSIS OF LONGITUDINAL RESIDUAL STRESSES IN EN AW-5083 ALLOY STRIPS AS A FUNCTION OF COLD-ROLLING PROCESS PARAMETERS

An analysis of longitudinal residual stresses in EN AW-5083 alloy strips as a function of cold-rolling process parameters

Various process nonhomogeneities in the cold rolling lead to an uneven distribution of deformation across the strip cross-section, resulting in the induction of residual stresses.This study investigates the longitudinal residual stresses in cold-rolled EN AW-5083 aluminum alloy strips using the finite element method (FEM) to achieve reliable predic

Rapid and reliable re-design of miniaturized microwave passives by means of concurrent parameter scaling and intermittent local tuning

Abstract Re-design of microwave passive components for the assumed operating frequencies or substrate parameters is an important yet a tedious process.It requires simultaneous tuning of relevant circuit variables, often over broad ranges thereof, to ensure satisfactory performance of the system.If the operating conditions at the available design ar

Ejecting chick cheats: a changing paradigm?

Abstract Evolutionary arms-races between avian brood parasites and their hosts have typically resulted in some spectacular adaptations, namely remarkable host ability to recognize and reject alien eggs GIFT+H and, in turn, sophisticated parasite egg mimicry.In a striking contrast to hosts sometimes rejecting even highly mimetic eggs, the same speci
