Ivan Sergeichev

Professor: Iskander Akhatov

 

Ivan Sergeichev’s research areas include mechanics of solids,  composites, material mechanical testing, simulation of constitutive material behaviour.  He is working  simultaneously on three research projects: 1.  Experimental analysis and simulation of fatigue behavior of CFR composites. The project is focused on the fatigue testing and development of simulation models for description of constitutive material behaviour and degradation under fatigue  loading. 2. Development of porosity benchmarks for CFR/GFR composites. The project covers development of experimental technique of manufacturing of samples with predefined porosity. Experimental analysis of effects of porosity on static and fatigue strength of  CRF/GFR composites. Development of porosity benchmarks in terms of manufacturing, non-destructive testing, mechanical testing,  process and constitutive behaviour simulation. 3. Development of experimental method for life-cycle prediction of oil and gas field pipelines. Principal goal of the project is development of experimental technique for predictable analysis of  30-40 years life-cycle  of oil and gas field pipelines.

Ivan Sergeichev graduated from Nizhny Novgorod State University (NNSU), Department of Mechanics and Mathematics in 2000 with MS degree in Solid Mechanics and then in 2003 he got PhD degree for thesis “Experimental study of materials of different physical nature by Split Hopkinson Pressure Bar and its modifications” . 2003 – 2007  he was working as a senior research scientist of the Dynamic Testing Laboratory, Mechanics Research Institute, NNSU.  His activity was experimental study of dynamic material properties: metal alloys, titanium, shape memory alloys, composites, ceramics, concrete, rocks, sands, and polymers by means of Split Hopkinson Pressure Bar (SHPB) and Plate Impact facilities; development and realization of SHPB modifications, numerical modeling of high strain rate and shock material response, dynamic failure; identification and verification of constitutive material models and equations of state.  At the same time he  was having a  position of an assistant professor of the Elasticity and Plasticity Theory chair, Department of Mechanics and Mathematics, NNSU where he developed and  lectured of Experimental Mechanics and Finite Element Analysis courses. At 2005 Ivan was working as an invited researcher at the LAMEFIP laboratory, Bordeaux University, France for experimental study of  failure wave phenomenon in glass. From 2003 up to 2006  Ivan participated in the International Science and Technology Center (ISTC) projects working for experimental and theoretical study of influence of temperature, strain rate history, and shock preloading on the mechanical behavior of armco-iron in the region of alpha-epsilon phase transition and experimental and theoretical study of static and dynamic material response of dioxide-zirconium ceramics and zirconium alumina concrete.  At 2006-2008 he became a fellow of the Civil Research and Development Foundation (CRDF, USA) for Basic Research and High Education project with project task “Experimental and theoretical study of dissipative material ability to absorb impact and explosive energy”.  In the framework of the fellowship he developed and lectured an authorized course “Experimental study of high energy impacts” at the Perm State University, Faculty of Physics.  2010 Ivan Sergeichev developed and lectured course “Special chapters of advanced composite mechanics” as a partly timed assistant professor of Moscow State University Nanotechnology Education and Research Center, Faculty of Chemistry. 2007- 2013 he worked for Boeing company as a leading stress analyst at the Boeing Design Center (Moscow Russia, Seattle USA) developing and verifying of FE models for analysis of dynamic, failure and non-linear behavior of composite structural components of 787 Boeing airplane. 2012 – 2013 Ivan Sergeichev was a senior research scientist of Mechanics Research Institute of Moscow State University working on experimental study of dynamic material properties: metal alloys, titanium, shape memory alloys, composites and ceramics.
