The purpose of the work is development of algorithm for solving the system of equations of bodies motion during collisions, analysis of the application of different models and identification of the flow characteristics of non-Newtonian fluids; development of methods, algorithms and applications programs for creep and damage analysis of avia- and space-rocket technique, which modeled as thin-walled beams. Research methods - theoretical and analytical mechanics, mechanics of deformable solids, numerical mathematical methods, as well as modern mathematical software. A method for researching of the dynamic creep by taking into account the damage parameter in the elements of aerospace and rocket technique, modeled by thin-walled beams under static and dynamic loads. Algorithms for solving problems of particles collision of arbitrary shape with solid surfaces have been developed. The connection between the yield strength and the shear stress on the pipe wall is presented. Formulas are obtained that allow to determine the required pressure, installation capacity and feed rate of the concrete mixture under the conditions of variable length of the plastic viscosity of the liquid and the time pressure variable at the inlet.
