Stress analysis and the safety of the modern economy

The article analyzes the role of continuum mechanics and stress analysis as the foundation of civilizational and economic security. Drawing on the theory of Emil de Souza Sánchez Filho, the author indicates that a rigorous tensor approach allows for an objective assessment of technical risk, eliminating imprecise rhetoric in infrastructure management. The text links classical field theory and tensor invariants with modern Industry 4.0 solutions, such as digital twins (ISO 23247 standard) and FEM simulations. Stress analysis is presented not only as an engineering tool but as an essential cognitive infrastructure that allows for the precise determination of asset durability and the costs of potential catastrophes in the world of heavy industry.
