It is known that for the description of the kinetics of processes of crystallization of melts of metals, low molecular weight materials, etc., the experimentally validated Kolmogorov-Avrami equation [45, 46] is often used, which for the above-mentioned symbols will have the form: (31) where – the value of the total mass of gas hydrates at the time t; z – constant rate of crystallization; n – coefficient dependent on the mechanism of formation and growth of crystals.

The diameter of the bolt shank is 10mm, the material yield strength is 785MPa.
The contact in the model of bolt connecting and the nonlinear of material’s constitutive relation bring on the result that the elastic-plastic deformation of the structure has relation with the time history of loading.
