Mechanics and machine scientist; corresponding member of the Academy of Sciences of the Ukrainian SSR from 1973. He studied and taught at the Kharkiv Polytechnical Institute. He headed the Kharkiv branch of the Institute of Thermodynamics of the Academy of Sciences of the Ukrainian SSR (from 1971) and became director of the Institute of Mechanical Engineering Problems of the Academy of Sciences of the Ukrainian SSR (in 1972). His main contributions are in the fields of dynamics and the strength of machines (see Machine science). He developed mathematical methods of solving nonlinear equations in the theory of plastic deformation and creep, which helped in the understanding of failure mechanisms in loaded structures. He worked also on methods of hydrogen utilization in engines.
