Zasovenko A. Resilient and resiliently-plastic waves in bar constructions

A research object is bars which co-operate with different grounds, or between itself, and are under the action of the different transversal loadings of shock type, or mobile loadings, that move with different speeds. The article of research is dynamic tasks about excitation the shock or mobile loading of resilient and resiliently-plastic waves in elaborate bar designs. Research methods: for the decision of tasks generalization of numeral method which is based on the use of descriptions of the determining systems of equalizations and итерационного approach is used, at specified type of contact the method of N'yutona-Kantorovicha. Research of influencing of stratification and physical parameters of elements of bar constructions is conducted on character of dynamic co-operation of their constituents in resilient and resiliently-plastic areas under the action of the different transversal loadings. The decision of wave task is got about the action of the mobile loading with different speeds on a beam from resilient and resiliently-plastic material. The pictures of development of areas of plastic deformation, and also distributing of tensions, are got in the transversal cut of beam. It is inculcated on SE "Іvchenko-Progress". The sphere of the use is an engineer.
