Structural Suitability Analysis of Metals and Alloys: Communication 1

Аннотация

The basic principles for assessing the structural effectiveness of the mechanical properties of metals and alloys in structural elements (SE) bearing a power load are described in two parts of the article. In the communication 1, the force “survivability” of loaded SEs under the influence of inhomogeneous force fields (IFF) was considered. A quantitative measure of a metal’s structural suitability is given, which is responsible for the integrity of the product with stress concentrators (SC), including cracks. The concept of elastic and elastoplastic (deformation) strength capacities is introduced, which give metals the properties of mechanical stability and deformation resistance, which serve as effective IFF compensators in the vicinity of the SC and ensure the integrity of the products.
