Dear readers, On 2228 August 2006, the IX All-Russian Congress on Theoretical and Applied Mechanics took place in Nizhnii Novgorod, Russia. The organizers of the Congress were the Russian National Committee on Theoretical and Applied Mechanics, the Russian Academy of Sciences, the RF Ministry of Education and Science, and the RF Ministry of Industry and Energy. The Congress gathered famous researchers and scientists in mechanics from all over the world. The participants reviewed the results obtained in theoretical and applied mechanics for the last five years after the VIII Congress. The state of the art in mechanics and the short- and long-term prospects for its development were discussed. The program included four sections: general and applied mechanics, mechanics of liquids and gases, solid mechanics, and complex and special disciplines of mechanics. The Congress has convincingly demonstrated that mechanics is a multidisciplinary field of science describing the motion of all real-world systems. Mechanics has entered into all branches of science and is a fundamental basis for numerous contemporary engineering problems. This required the development of completely novel approaches and methods of mechanics both for analytical solutions and numerical simulation. Detailed information on the Congress is given in an analytical review of Academician D.M. Klimov published in the Herald of the Russian Academy of Sciences (Vol. 77, No. 5, 2007). This issue of our journal presents some plenary reports on topical problems of solid mechanics. They discuss the key trends in modern theoretical and applied mechanics: the development of analytical and numerical methods of continuum mechanics, consideration of a deformed solid as a multilevel system, application of new approaches to describing the behavior of heterogeneous media under different loading conditions. The subject of the reports in the present issue can be interesting for specialists in mechanics, physics, geophysics and geotectonics, modern materials science and various engineering applications. Editors of the issue: Academician of RAS Victor E. Panin, Professor Robert V. Goldstein
