Project summary

In Russian Federal Nuclear Centres VNIIEF and VNIITF and also in RIM NNSU for many years versatile works on research of physical-mechanical properties of different materials are carried out. They are:
- static tests to define mechanical characteristics (Young modulus, Poisson's ratio, ultimate strength and yield strength, residual elongation, and reduction) and deformation diagrams;
- impact tests and fatigue tests;
- research of limp-strain state with method of acoustic emission;
- long-time and short-time creep tests;
- definition with Kolsky method of dynamic dependencies "stress-deformation"at different temperature-time loading conditions;
- investigation of materials resistance to plastic deformation with Tailor method at deformation rate up to 104 1/s and with method of main stresses at deformation rate up to 106 1/s;
- definition of spalling and shear strength of structural materials;
- study of elastic anisotropy of parts materials with ultrasonic impulse method;
- study of temperature-time relationships of structural materials dynamic fracture process under the influence of heat shock ( energy input rate is up to 1011 J/gґs);
- investigation of joint influence of high temperatures (up to 873 K) and hydrogen pressure (up to 200 MPa) upon mechanical characteristics and parameters of metals permeability to hydrogen;
- study of thermal physical properties of structural materials (thermal expansion, enthalpy, relative electroresistance, specific heat, thermal and temperature conductivity ratios are defined in one test on one sample);
- obtaining of probabilistic characteristics of structural materials properties;
- making of chemical, element and metallographic analysis of samples.

Recognised researchers in the field of investigation of physical and mechanical properties of materials take part in this work: B.L. Glushak, V.A. Sinitsin, Ju.V. Batkov, A.P. Bolshakov, N.A. Bilyk, Ju.A. Habarov, N.I. Zavada, N.N. Popov, A.I. Korshunov, V.G. Didenko, G.P. Horoshkina, N.Ja. Michailov, Je.K. Bonyushkin, A.Ja. Uchaev, A.N. Lebedev, A.M. Bragov, A.K. Lomunov, Ju.G. Korotkih.

The results of many studies are published in collections of CSRI atominform, Reports of Academy of Science, the journal "Strength Problems", in interinstitutes collections of Nizni Novgorod State University, and in reports at international conferences and in other sources.

The aim of project is to create a united automated data bank (DB), containing standard references, recommended references and informational data on physical-mechanical properties of materials.

It is expected to insert into DB physical-mechanical characteristics, thermal properties, chemical composition and density of metals, wood, steals, alloys of non-ferrous metals and plastics.

The information that is inserted into data bank will contain the description of all necessary attributes, refining the conditions and special features of obtaining the properties. The material properties can be presented in the form of a single value, a set of values or in the form of a plot.

At the initial stage DB will contain the following information for description of mechanical properties:

· type of research (data processing methods);
· research mode or data processing parameters;
· class of materials;
· form and dimension of a sample or construction element;
· working surface processing;
· denomination of material;
· conditions of research;
· thermal processing;
· chemical composition;
· the way of obtaining and spacing the blank;
· photo materials characterising the tests (factography of fracture, etc.).

The given properties shall be presented in the form of:

· tables of plots;
· mechanical properties;
· materials certificates;
· bibliography.

DB structure will be opened, i. e. the possibility of inputting new additional kinds of stored information, transformation of data from one form into another will be provided for.

DB will have reference-book of measurement units and counting.

Besides computer DB carriers, it is expected for materials studied in RFNC-VNIIEF and VNIITF to publish a reference book in which the already known and also not published data on physical-mechanical properties of materials can be introduced in a wide range of initial temperatures (-196 ºС — +800 ºС) and deformation rates from 10-4 1/s to 107 1/s, and also the description of research methods of physical-mechanical properties and mathematics models of materials behaviour.

Task solution includes collection, analysis storage and classification of existing data, software design, conducting additional experimental investigations either to confirm the data needing adjustment or to define missing data, improvement of existing and development new mathematic models of materials behaviour description at highspeed loading.

The role of foreign partners is very important in assistance of purchasing the samples, investigated to their methods, materials and in carrying out comparable analysis of defined on them data on home installations to find out the truth of obtained either in Russia or abroad results especially at high-speed loading.

Foreign partners could help to obtain the information of physical-mechanical characteristics of their (uniformal in chemical composition to ours) materials to include them into DB, comparable analysis that would permit to accelerate scientific-technical progress in materials science either in Russia or abroad.

The result of the work will be DB enlarging our knowledge of reological properties of materials and, by this, substantially enlarge the truth of reliability and safety prognosis for constructions which are under exposure either high static or intensive dynamic loading and work in wide thermal regime, and also metals and alloys incorporated in fuel elements of atomic power stations and ensure rational choice of materials to design the new or improve existing constructions.

Specifically, the results of investigation with thermal shock method can be used designing accelerators of charged particles, when study the problems arising at the impact of powerful laser impulses on the matter to define the longevity of the first wall of thermonuclear reactor, and also for prediction of fuel elements thermomechanic resistance, connected with emergency and preemergency situation at atomic power stations when fragmentation of active materials is possible.

Specially designed software of DB will allow to use data on physical-mechanical characteristics for the very deversed calculations. And also the researcher does not need to solve programmistic questions of storage and data search.

Publication of the reference-book will allow to provide the more optimal selection of materials and the most effective methods of calculation of strength, to develop more advanced recommendations for constructions being in contact with intensive mechanical and thermal loads.

Practical significance of the reference-book is obvious for prediction of materials behaviour reologic properties of which are not completely studied in abovementioned amount.
