Influence of Josephson current second harmonic on stability of magnetic flux in long junctions

We study the long Josephson junction (LJJ) model which takes into account the second harmonic of the Fourier expansion of Josephson current. The dependence of the static magnetic flux distributions on parameters of the model are investigated numerically. Stability of the static solutions is checked by the sign of the smallest eigenvalue of the associated Sturm-Liouville problem. New solutions which do not exist in the traditional model, have been found. Investigation of the influence of second harmonic on the stability of magnetic flux distributions for main solutions is performed.Comment: 4 pages, 6 figures, to be published in Proc. of Dubna-Nano2010, July 5-10, 2010, Russi

Power Intensification of Swelling Process

DergiPark: 245958trakyafbdMakale, boru şekilli bir parçanın şişirilmesinde ilave eksenel basınç uygulayarak güç yoğunlaştırmanın etkilerini araştırmak üzere yürütülen çalışmaların sonuçlarını özetlemektedir. Eksenel basıncın arttırılması, ?? gerilme indeksini ve gerilme halinin rijitliğini azaltarak şekil değiştirme bölgesindeki malzemenin düzgün akışını sağlamaktadır. Bu yöntemle düşük karbonlu çelik parçalar için, şişirme indeksinde % 15 civarında bir düşüş ve şekillendirilebilirlikte % 76 ile % 78 arasında bir artış elde edilmektedir.The paper deals with the outcomes of investigations carried out to determine the impact of power intensification of a deformation process by means of applying additional axial pressure over the fronts of round billets. By increasing axial pressure, the value of ?? index and the “rigidity” of the stressed state pattern drops down that promote redistribution of metal within the area of deformation. This resulted in 15% decrease of the index of swelling and 76 to 78% increase of the permissible level of swelling during deformation of low carbon steel specimen
