| Abstract |
Dyuis Danilovich Ivlev was born on September 6, 1930 in Cheboksary. He
graduated from the Faculty of Mechanics and Mathematics at Moscow State
University in 1953, completed his postgraduate studies there, and defended
his Ph.D. thesis in 1956 (Moscow State University) and D.Sc. Thesis in
1959 (Moscow State University).
Ivlev's research deals with mechanics of deformable solids, mainly, with
the mathematical theory of plasticity and limiting states of solids. He
developed the general theory of limiting statically determinate states of
solids. This theory is based on the mathematical technique of equations of
hyperbolic type, which is quite adequate to the shear character of plastic
strain related to the formation of slip plateaux along slip surfaces. The
results were generalized to anisotropic and compressible media and to
separation fracture. Discontinuous solutions for the space state of
perfectly plastic solids were studied, and solutions of a wide class of
problems on the indentation of rigid dies and bodies into a perfectly
plastic half-space as well as on the limiting space state of a material
compressed between rough plates, etc. were given. The studies of
stationary and nonstationary flows of perfectly plastic media gained
further development.
Considerable attention in Ivlev's papers is paid to duality issues,
pertaining to the equivalent construction of plasticity theory on the basis
of the definition of the loading function and the associated plastic flow
law or the definition of the dissipative function and the associated
loading law. The postulates underlying the construction of plasticity
theory and resulting in the associated flow and loading laws were analyzed.
In the theory of strain-hardening plastic media, Ivlev developed the
concepts based on the translational hardening mechanism and put forward by
Ishlinskii and Prager. A series of papers deals with linear problems of
elastoplastic and rigid-plastic states. A successive approximation
algorithm was developed permitting one to obtain solutions of 2D,
axisymmetric, and 3D problems. A series of studies deals with deformation
theory of plasticity, the construction of models of elastic and viscous
media, statics and dynamics of free-flowing media, mechanics of
quasibrittle fracture, etc.
Ivlev published over 200 scientific papers. His results are a fundamental
contribution to mechanics of deformable solids. Ivlev played an important
role in the advent of scientific schools on mechanics in Voronezh,
Cheboksary, and other Russian cities. There are doctors and candidates of
sciences among his students.
The editorial board and the Editors of Mechanics of Solids cordially
congratulate Dyuis Danilovich on his seventy-fifth birthday and wish him
sound health and many new scientific results. |
