The basic parities of differential geometry for the cover of nuclear reactor at calculations durability
He conclusion of the basic parities of differential geometry not flat ellipsoid the bimetallic shell of rotation modelling a cover of a nuclear reactor is given: expressions for factors of the first and second square-law forms of a surface join, for factors to the Lame, the main radiuses of curvature are received, their justice on the basis of performance of parities Kodazzi-Gauss is confirmed.
