Mathematical models and solving methods of the static and dynamic stress-strain state in composite shell structures for different purposes especially for problems in tire mechanics

Objective



The participants from the NIS will make available their fund of theoretical and numerical knowledge in the above- mentioned fields for actual technical and ecological problems, existing in the NIS and in the INTAS member states.

They will to carry out fundamental research for the solution of theoretically pretentious problems in composite shell mechanics, especially in tire dynamics. This includes the creation of effective models for computation and new analysis methods for the dynamic behaviour of the rolling tire in contact with rigid or pliable supporting surfaces and for solution of difficult problems of non-linear shell dynamics.

The following themes will be developed:

- Verification of the adequacy and bounds of application of simplified models for the static and dynamic behaviour of composite shells by solving the corresponding three-dimensional problems with modern methods of computational mechanics of composites;
- Improving the theory of laminated rubber-cord pneumatic shells for the calculating methods of stress and heat state analysis in radial tires. Creation of fast object-oriented program systems for automated design and determination of tire characteristics;
- Developing non-linear Timoshenko/Mindlin-type and discrete theories of multilayered anisotropic shells of revolution. Investigation of the static and dynamic behaviour of prestressed non-symmetrical loaded pneumatic tires of low pressure and of some technological problems of tire mechanics;
- Computation methods and analysis of the stress-strain state and dynamic behaviour of shell elements in composite structures. Static and dynamic behaviour of multilayered thin and thick shells with application to pneumatic tire mechanics.

The expected results will be presented in the form of scientific papers, books, lecture notes and computer programs.

The activities are aimed at innovative scientific results of high originality, at application in tire dynamics and also at practical exploitation for avoiding the "hammer"- effect of truck tires on highway surfaces and for soil preserving use of tires in agriculture, forestry and landscape cultivation (in the sense of terramechanics).
