Abstract |
May 7, 2010, is the seventieth birthday of
Robert Veniaminovich Goldstein,
Corresponding Member of the Russian Academy of Sciences.
In 1962, R. V. Goldstein graduated with honors
from the Faculty of Mechanics and Mathematics of Lomonosov Moscow State University
in the speciality mechanics.
Since that time his life has been full of scientific activities in the Academy of Sciences.
He began as a post-graduate student at the Institute of Mechanics,
Moscow State University (1962-1965);
then he was a scientific researcher at the Institute for Problems in Mechanics (since 1966),
where, since 1988, he has been Head of Laboratory on Mechanics
of Strength and Fracture of Materials and Structures organized by him.
In 1968, R. V. Goldstein defended his Ph.D. thesis
"Surface Waves and Resonance Phenomena in Elastic Bodies"
(his scientific supervisors were G. I. Barenblatt and R. L. Salganik),
and in 1983, he defended his D.Sc. thesis
"Studies in Fracture Mechanics of Large-Size Structures."
R. V. Goldstein's papers in mechanics of solids and
in the field of its applications are widely known in our country and abroad.
He obtained fundamental results in mathematical and dynamical theory of elasticity,
fracture mechanics, mechanics of materials,
mechanics of ice and ice cover,
micro- and nanomechanics, and mechanics of contact interaction
of deformable solids.
In the field of dynamical theory of elasticity,
R. V. Goldstein studied the resonance phenomena in elastic bodies
that accompany the crack propagation and the motion of loads and indentors
with velocities close to the Rayleigh velocity.
Considering the nonstationary stage of load motion
on the half-space boundary, he analyzed specific characteristics of elastic fields
that arise in the process of stabilization near the Rayleigh velocity,
which allowed him to explain the resonance phenomena observed
in transition through the Rayleigh velocity.
He discovered and studied the resonance phenomena observed in the case
of crack propagation along the interfaces between materials with
different elastic properties.
It turned out that the characteristic velocities,
typical of different modes of crack propagation,
are the Rayleigh velocities for each of the contacting materials,
the Stoneley wave velocity, and the velocities of surface waves
due to incomplete contact of materials at the interface
(the sliding condition on the interface
and the conditions of possible separation of materials from each other with no slip).
In the last case, he found a new type of surface waves.
Later, these waves were registered in some earthquakes.
A large cycle of papers by R. V. Goldstein, V. M. Entov, and E. I. Shifrin
were devoted to the development of qualitative methods of elasticity and fracture mechanics
that permit constructing two-sided and isoperimetric estimates
of local and integral characteristics of solutions of the corresponding spatial problems and,
in particular, estimating the stress intensity factors for cracks of complicated shape
and finding sufficient conditions for structure fracture or nondestruction.
The results obtained by R. V. Goldstein and V. M. Entov were summarized
in the monograph "Qualitative Methods in Continuum Mechanics" (1989, in Russian),
which was translated into English and published in England in 1994.
R. V. Goldstein developed methods for asymptotic and numerical solution
of spatial mixed problems of elasticity,
including the problems with unknown boundaries.
He developed efficient projection methods for numerical solution
of boundary integral equations and minimization of boundary functionals
of spatial problems in crack statics and mechanics.
In collaboration with his colleagues and pupils,
R. V. Goldstein implemented these methods
as packages of applied programs that are successively used
to compute the crack behavior in structural elements.
Methods for matched asymptotic expansions were developed to solve
three-dimensional problems of elongated cracks in elastic space and in a layer.
Methods for studying and solving three-dimensional contact problems
and problems on cracks with friction, sliding, adhesion, and loading history effects
taken into account were proposed in joint papers with Yu. V. Zhitnikov and A. A. Spektor.
R. V. Goldstein developed several models of material and structure fracture.
He proposed a semiempirical method for describing fracture of
elastoplastic materials with cracks and formulated similarity criteria
that permit estimating the fracture conditions
for large-size structural elements with cracks
from the results of tests with their scaled-down models.
He developed a new approach for modelling the fracture
and estimating the safety of hierarchical systems.
The formation of structures of brittle and quasibrittle fracture
of materials (media) with their structure under complicated loading
(in particular, under multi-axial compression) taken into account,
was modeled in the cycle of papers
written in collaboration with N. M. Osipenko.
Models of fracture under compression conditions for thin bodies,
systems with coating, and natural objects such as ice cover
were also developed.
The forms of ice cover fracture under the simultaneous action of wind load and
the loads caused by the interaction between the ice cover
and the icebreaker or a sleetproof construction were classified.
Since the beginning of the 1990s,
R. V. Goldstein
obtained, in collaboration with his pupils and colleagues, a series of fundamental results in the field
of nano- and micromechanics of strength and fracture of materials and structure.
These investigations were primarily aimed at the solution
of strength and life support problems
for micro- and submicroelectronics products.
The models were developed and degradation processes arising
in multilevel interconnection wiring (conductor lines)
in micro- and submicroelectronics products
due to the action of mechanical loads and electromigration
were modeled.
The interconnection wiring life was estimated.
The fracture conditions for chip-scale enclosures
were modeled under thermomechanical loading.
The influence of point defects
on the adhesion characteristics in thin-film structures
and the conditions resulting in strengthened heterosystem formation
in plates (Si substrata) were modeled,
and discrete-continuous models of the mechanical behavior
of nanotubes and their systems, of graphene plates and their sets,
were developed.
A generalized model of atomistic crack was proposed
and conditions for the continuum approach of the crack theory
to be applicable for describing the nanoscale crack growth conditions
were obtained.
The results of R. V. Goldstein's fundamental studies
are successfully used to solve applied problems.
Since the 1990s, R. V. Goldstein
(from 1975 to 1990, he was the scientific supervisor
on behalf of the Institute for Problems in Mechanics, Russian Academy of Sciences)
actively participates in complex projects
performed in collaboration with leading specialized organizations
in the field of special technology and equipment
for transportation, preparation, and processing
of hydrocarbon raw materials (1976-2000).
As a result of these investigations,
several normative documents on the standardization
of admissible defects
in critical products and structures
and on the estimation of their life
under mechanical loads and active environmental action
were developed and then approved by the appropriate agencies.
As an expert, R. V. Goldstein repeatedly participated
in Russian State Commissions on analyzing catastrophic fractures
of different complicated technical systems and
on working out measures for their prevention.
The results of R. V. Goldstein's studies
were published in more than 330 scientific papers,
and over 150 of them were published
in peer-reviewed Russian and international journals.
R. V. Goldstein pays great attention to young scientists.
He created one of the leading schools in the Russian Federation
in the field of strength and fracture mechanics,
and 18 Ph.D. theses and 5 D.Sc. theses were defended
under his supervision.
Since 1983, R. V. Goldstein has been combining his scientific activities
with teaching as Professor at
MATI- K. E. Tsiolkovskii Russian State Technological University.
R. V. Goldstein was one of the initiators of the project
to open a MATI branch of the Chair of Physics at the Institute for Problems in Mechanics (IPM),
Russian Academy of Sciences (RAS),
with the goal of educating scientific personnel specializing
in the field of strength and fracture of materials and structures.
As head of this chair branch and IPM RAS head
