Scientific development prof. Iskakbaev A.I. devoted to the important fundamental problem: the study of creep and long-term strength of materials with arbitrary voltage over time. The author suggested that development of the concept of functional failure Rabotnov and L.M. Kachanov. Proposed by the author of the new approach allows us to describe the deviation from the principle of linear summation of the partial times Bailey Robinson. Based on the synthesis of the theory of functional fracture-Rabotnov Kachanov and theories of brittle fracture Cherepanov, the author managed to relate the two different fracture process arising from the accumulation of scattered damage and the spread of the main crack. The author developed a mathematical model of evolutionary degradation in rock mechanics.

Space Engineering and Technology
Space activities have become one of the leading sectors of the economy. Advances in exploration and exploitation of space are one of the most important indicators of development level of countries.
The major areas of space activities are:
- space research - use of space technology for communications, television and radio broadcasting - Earth remote sensing from space, including environmental monitoring and meteorology -the use of satellite navigation systems and top geodesic;
- manned spaceflight; -observation of objects and phenomena in outer space; -test equipment in space; -production in space materials and other products; -the creation of rocket and space technology; - Other activities carried out by using space technology
Spacecraft remote sensing used to study the Earth's natural resources and solving problems of meteorology. Spacecraft to study the natural resources are equipped with mainly optical or radar equipment. The advantages of the latter lie in the fact that it is possible to observe the Earth's surface at any time regardless of the state of the atmosphere.
In the process of learning is a widely used modern technology of teaching. Material-technical base meets the modern requirements of this branch of science and promotes the full development of the educational program.
Space activity includes the creation (including the design, fabrication and testing), use (operation) of space technology, space materials and space technologies and the provision of other space-related services, as well as international cooperation of the Republic of Kazakhstan in the exploration and use of outer space.
