To the theory of creepage and long-lived strength of concrete

In the paper the energetic theory of nonlinear creepage and long-lived strength of cracking materials worked out by V.D.Harlab has been considered. The author has proposed some changes permitting to avoid overstrains of the theory by intermediate arguments and to simplify application of the theory to calculation practice.

Off-centre way of formation of vessel movement equations

Movement equations have been formulated as applied to vessel manoeuvrability. Movement equations have been considered to be classical ones of rigid disc dynamics. The rigid disc possesses its own inertiality and is influenced by active forces of the mover and reactive forces of surrounding water including inertial forces as well. There is a difference from the traditional point of view which considers movement equations to be equations of inertial equilibrium of the system "vessel – surrounding liquid". Some specificity in co-ordinates' choice has also taken place in the paper.

On modeling of forces influencing on a moving vessel

The results of numerical modeling of a thermal mode of object of long-term storage of the spent nuclear fuel in a variant of the built in ferro-concrete design have been presented. Proofs on maintenance of a safe thermal mode of object in the conditions of the chosen configuration for a wide range of parameters of model have been set.
