Boris D. Annin is a well-known scientist in the mechanics of deformable solids. He has achieved fundamental results in solving the elasto-plastic problems. Boris D. Annin has offered an approach which allowed proving the existence and uniqueness of the theorem for the solution for the arbitrary convex shape. Using the theory of variational inequalities, he has created 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 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.

He has 100 publications, including 6 monographs.
