    Two titanium alloys, the α+β Ti6Al4V and the α phase Ti5Al2.5Sn alloy, have been irradiated at 150°C with neutrons, in the reactor of the Atomic Energy Research Institute, in Budapest and with 590 MeV protons in the PIREX ...
  • Fracture toughness of multilayer pipes 
    Nezbedova, E.; Fiedler, L.; Majer, Z.; Vlach, B.; Knesl, Z. (Проблемы прочности, 2008)
    Multilayer pipes composed of various materials improve partially the properties of a pipe system and are frequently used in service. To estimate the lifetime of these pipes the basic fracture parameters have to be measured. ...
  • Fracturing of the Crust — Geological and Geophysical View 
    Milanovsky, S.; Nikolaevskiy, V. (Геофизический журнал, 2010)
  • Fragmentation fractal of sandstone under acid corrosion and coupled static-dynamic loads 
    LIU Yong-sheng; LI Jin; ZOU Jia-yu; WU Yun; LU Shao-yong (Functional Materials, 2018)
    The analysis results show that the fragment of broken rock is a fractal distribution, and the smaller the impact pressure is, the less specimen fragments is,the lower degree of fragmentation degree is, and the lower fractal ...
  • Fragmentation of thin lenses 
    Brodskii, R.Ye.; Kulik, T.V. (Functional Materials, 2016)
    In the paper it was investigated the case of the quasi-two-dimensional fragmentation - fragmentation of the round lenses considering dependence of the probability of splitting on energy required for this, i.e. the surface ...
  • Fragmentation of thin plates by dot impact 
    Brodskii, R.Ye.; Kulik, T.V. (Functional Materials, 2015)
    In this paper we study the case of two-dimensional single-impact fragmentation, namely the fragmentation of the circular thin plate by dot impact. The distribution density of the fragments by mass was obtained analytically ...
  • Framework of language learning strategies in the cultural context 
    Knyazeva, N. (Культура народов Причерноморья, 2001)
    Статья посвящена методологическим проблемам, учитывающим когнитивные и культурные аспекты при изучении английского языка как иностранного. Для обучаемого любой разговорный опыт с носителем языка является формой ...
  • Frattini theory for N-Lie algebras 
    Michael Peretzian Williams (Algebra and Discrete Mathematics, 2009)
    We develop a Frattini Theory for n-Lie algebras by extending theorems of Barnes' to the n-Lie algebra setting. Specifically, we show some sufficient conditions for the Frattini subalgebra to be an ideal and find an example ...
  • Frechet Similarity Between Two Ambigiously Defined Polygonal Lines 
    Vodolazskiy, Ye.V. (Control systems & computers, 2021)
    The paper considers the problem of comparing two polygonal lines that are not strictly defined. Instead, two sets of polygonal lines are given assets of paths on two acyclic directed graphs. The problem is to determine ...
  • Fréchet-valued holomorphic functions on compact sets in (DFN)-spaces 
    Pham Hien Bang (Український математичний журнал, 2008)
    The aim of this paper is to give the equivalence between the weak holomorphicity and the holomorphicity of Frechet-valued functions on compact polydiscs in (DFN)-spaces. Moreover, the relations between separately holomorphic ...
