hybrid cores, hybrid farm designs, durability of operation, long durability, creep, theory of aging, isochronous curve deformations, maximum permissible deformations, maximum permissible durability, efforts of movement, deformation

On the basis of the idea of construction and use of isochronous curves of deformation samples of uniform materials at long loading taking into account possible degradation with time of properties of materials, developed the scheme of forecasting of durability of hybrid cores various materials made of set. The scheme is used for obtaining extreme durability hybrid farm designs from a set of various materials.
