Abstract
The article briefly examines the construction process as an activity of creating a material image of an object, which is developed in the form of a full-scale model and its graphic representation: drawings, computer models.
The article considers the main ways of ensuring strength: empirical; experimental, which includes planning and certain amount of calculations, and calculation, in which the empirical component is minimized due to the appropriate theoretical apparatus, and with the development of science and technology, its role increases.
It is noted that when calculating strength, it is necessary to solve the following problems consistently and in mutual agreement: the problem of external forces; the stress determination problem and the allowable stress problem.
Solving the problem of calculating the stress-strain state requires knowledge of the mechanical constants of the construction material, and the normalization of stresses - its strength characteristics.
The main content of the article includes the presentation of some methods and means of measurement developed in the laboratory of polymer composite materials of the Kherson State Maritime Academy to ensure research work on the creation of composite materials for shipbuilding with increased operational characteristics.
These studies include experimental determination of physical and mechanical properties of the materials being created, which requires special testing equipment. This task was largely solved by the laboratory team by renovating the existing equipment, automating its operation and analyzing information using computer and engineering graphics, as well as developing new methods and means of measurement. Technological designs of samples and methods of determining the mechanical constants of polycrystalline and composite materials are proposed.
The developed technical solutions are protected by patents, the implementation of which provided a significant positive effect.
