The scientific novelty of the project and its fundamentality lies in the fact that the project is based on original ideas and concepts, namely: the idea of ​​building universal design models of massive and thin-walled structures of inhomogeneous structure; on the idea of ​​using the semi-analytical version of the ITU to describe the stress-strain state of canonical bodies, on the idea of ​​presenting the criterion parameters of fracture mechanics due to the magnitudes of nodal reactions and displacements that are a direct result of solving the ITU problem. values ​​of stresses and strains by numerical differentiation. The advantage of the results obtained, in contrast to the known approaches, is the ability to analyze the crack resistance of massive and thin-walled structures of inhomogeneous structure under the influence of temperature and bulk loads. The results are attractive for investment, have significant scientific and practical value, can be used by specialists in both structural mechanics and related industries. They can be used in construction, aircraft and mechanical engineering to create tools for computer simulation of the operation of critical structural elements.
