The effective analytical methodic of realization of the designed theory is constructed, on the basis of which the influence deplanation of sections on parameters of stress-strained state of bars both homogeneous, and complicated composite structure is investigated. The designed theory is used for the decision of practical engineering tasks, in particular for: definitions of criteria of loss both overall stability composite bars, and its separate phases under condition of destruction of a matrix; a determination of parameters own and forced vibrations of composite bars with the account deplanation of sections; creations of a methodic of experimental researches of composite systems, compliant transversal swaging etc. The methodic of definition of phisical and mechanical properties "Sandwich" - elements with metal external layers and basalt cotton wool as midlle layer is developed, on the basis of which the system of quality of their manufacture is created. The experimental research of mechanical resistance of a stratified ceramic aggregate to static curving is realized. The methodic of the decision of an inverse task is developed which on the basis of an experimental dat& of deformation of a stratified ceramic composite girder - sample has allowed dates an estimation of its mechanical performances.
