Research & development in the field of marine composite structures.Strength and nonlinear behaviour under multiaxial loading were considered for testing and structural analyses. Development of micromechanical models for syntactic foams:
C++ implementation for both mechanical solver and 3D postprocessor. The model considered detailed stress states of 10^5 elements of micro structure simultaneously to assess the development of damaging processes in foam material due to growing… Show more Research & development in the field of marine composite structures.Strength and nonlinear behaviour under multiaxial loading were considered for testing and structural analyses. Development of micromechanical models for syntactic foams:
C++ implementation for both mechanical solver and 3D postprocessor. The model considered detailed stress states of 10^5 elements of micro structure simultaneously to assess the development of damaging processes in foam material due to growing hydrostatic pressures.Supervision of multiple series of mechanical tests:- strength, elastic moduli, fatigue prop. of materials. - testing of GFRP, CFRP, foams and other lightweight core materials were tested- mechanical properties of "sandwich" structures.Monitoring of the new materials/construction production:- syntactic foams- multilayered hybrid glass/carbon type fabrics- composite structures- hull structure jointsDevelopment of new mechanical test methods. Project management: searching and dealing with new laboratories, contractors, research centers, etc. Show less

Parametric optimization of the reflective surface for the russian spacecraft called "Interheliozond". The goal was to limit optical aberrations under extreme thermal conditions so that the surface would satisfy strict optical criterions. That job made me really happy.Also i was conducting R&D for new composite structures in a number of a smaller projects.

Static / dynamic FE 2D/3D thermal + structural analyses. Parametric optimization was performed for chosen components.Almost every type of the engine components was analyzed both analytically and using FE method. Turbine, rotor parts: shafts, impellers, turbine blades, gears, bearing sets, splines, etc. Static parts: bearing stacks, air/oil seals, bolted joints, inlet cases, threaded connections, housings and covers, etc.Crack propagation analysis was conducted for parts with… Show more Static / dynamic FE 2D/3D thermal + structural analyses.

The engine was successfully assembled and tested. Show less
