Stresses, Strains and Energies in Areas of Concentration Under Prolonged Stretching of Structural Elements
The paper proposes an engineering method for calculating the local principal stresses, elastic viscous plastic strains and energies in areas of concentration under prolonged stretching of structural elements. The example of using the method at short-term and prolonged stretching of the rod with a circular notch is considered. It is shown that increasing the duration of loading leads to an increase in local strains and energies, and it reduces the long-term strength of the rod.
