In 1959 Boris D. Annin graduated from the Moscow State University, in 1962 he completed his postgraduate studies in Institute of Hydrodynamics. He became a candidate of science in physics and mathematics (PhD) in 1963, doctor in physics and mathematics in 1971, corresponding member of RAS since 2000. Now he works in Lavrentyev Institute of Hydrodynamics (since 1962).

Boris D. Annin is a well-known scientist, specialized in mechanics of deformable solids. He has 100 publications (as author or contributing author), including 6 monographs. Annin is best known for his fundamental results in methods of solving of elasto-plastic problems development. He has offered a new approach to the solving of classical problem of elasto-plastic torsion that allowed proving the existence and uniqueness theorem for the solution for the arbitrary convex shape. Using the theory of variational inequalities he has created and realized the effective numerical algorithms for solving the contact elasto-plastic problems on the dynamic loading of the composite boards and the glancing collision of plates. The methods of solving plane elasto-plastic problems on the stress concentration near the holes have been developed and allowed to find the plastic deformation areas near the mine openings on the base of suggested exponential yield condition, which approximates the limit state of rock formations well.

B.D. Annin has developed the unconventional models of deformation and failure of dispersal reinforced composite media, constructed the valid approximate equations of multilayered bodies elastic deformation and explicated the methods for synthesis of composites with given thermoelastic and strength characteristics.

B.D. Annin initiated the application of the Lie-Ovsyannikov group method in the mechanics of deformable solids; constructed exact solutions of plasticity equations are of great academic and practical importance.

Boris D. Annin developed in partnership the complex loading apparatus with self-programming of the stress state. This construction allowed conducting the experiments on the investigation of properties of new materials (tensile strength ship steels and composites) and traditional materials under the complex loading.

B.D. Annin widely participates in the scientific researchers’ education in Novosibirsk State University during 45 years. He took an active part in creation the department of applied mathematics and mechanics. Now B.D. Annin fills the position of the head of department of mechanics of deformable solids. He took the research supervision of 29 candidates of science and 5 doctors of sciences.

Boris D. Annin is fully engaged in research and administration, he leads the Institution nonstructural section of mechanics of deformable solids consisting of three laboratories and holds a position of co-director of the leading scientific school “Inelastic deformation and failure of non-homogeneous media and constructions”. B.D. Annin is a member of editorial boards of “Prikladnaya Mekhanika i Tekhnicheskaya Fizika” (“Applied Mechanics and Technical Physics”) journal of the RAS Siberian branch, “Sibirskii Zhurnal Industrial'noi Matematiki” (“Journal of Applied and Industrial Mathematics”), “Vestnik Novosibirskogo Gosudarstvennogo Universiteta.
