buckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Surrogate ratio methodology for the indirect determination of neutron capture cross sections
The relative γ -decay probabilities of the 162Dy to 161Dy and 162Dy to 164Dy residual nuclei, produced using light-ion-induced direct reactions, were measured as a function of excitation energy using the CACTUS array at the Oslo Cyclotron Laboratory. The external surrogate ratio method (SRM) was used to convert these relative γ -decay probabilities into the 161Dy(n,γ ) cross section in an equiv...
متن کاملNuclei cross sections in Extensive Air Showers
Abstract Cross sections for proton inelastic collision with different nuclei are described within the Glauber approximation. The significant difference between approximate “Glauber” formula and exact calculations with geometrical scaling assumption is shown for very high energy cross section calculations. According to obtained results values of proton–proton cross section reported by the Akeno ...
متن کاملDetermining neutron-capture cross sections via the surrogate reaction technique
Indirect methods play an important role in the determination of nuclear reaction cross sections that are hard to measure directly. In this paper we investigate the feasibility of using the so-called surrogate method to extract neutron-capture cross sections for low energy compound-nuclear reactions in spherical and near-spherical nuclei. We present the surrogate method and develop a statistical...
متن کاملMeasurements of interaction cross sections for light unstable nuclei
Recent experimental results concerning interaction cross sections (σI) are reviewed. σI values have been measured by a transmission method using the fragment separator at GSI. The σI values for B, C, N, O, and F isotopes are presented. By using Glauber-model analysis, the effective matter radii for light neutron-rich nuclei can be deduced. The recently shown magic number, N = 16, near the neutr...
