Nikolai V. Skiba - Leading Researcher - Laboratory of Nanomaterials Mechanics and Theory of Defects
Grants of the President of the Russian Federation for 2007, 2011 and 2016.
Acted as a head in the grants of the Government of St. Petersburg for young scientists (2002, 2004-2006, 2008, 2012 and 2013), RFFR grants for young scientists "My first grant" 2012-13 and support for young Ph. D 2016-19.
From 2016 to the present N.V. Skiba is a member of the editorial board of the scientific journal "Materials Physics and Mechanics".
N.V. Skiba is the author of more than 60 scientificpapers in leading academic and international scientific journals (Physics of the Solid State, Technical Physics Letters, Acta Materialia, Scripta Materialia, Phys. Rev. B, Int. J. Plasticity, Journal of Alloys and Compounds, Phil. Mag., Reviews on Advanced Materials Science, etc.) and 30 reports at international conferences and seminars. Within the framework of scientific activity at IPME RAS, theoretical models have been developed that describe new plastic deformation micromechanisms responsible for an unusual combination of ultrahigh strength and plasticity of nanostructured materials that is extremely important for practical applications. Also, theoretical models were developed to explain the key aspects of the plastic behavior of nanotwinned materials and composites with bimodal structure. For the first time, a theoretical description of the dependence of the yield strength on the parameters of the nanotwinned structure in nanotwinned materials is given, which makes it possible to develop recommendations for optimizing the structure of these materials in order to achieve a simultaneous combination of high strength and functional plasticity.
