Effects of Yield Variations on Strain Concentrations in Inelastic Response

摘要

Simplified and detailed inelastic analyses have been used to assess strain concentrations. Evaluations of beams, cylinders, notched sections, perforated plates, and shells revealed that predictions of inelastic peak strains are sensitive to the choice of yield strength. The extent of sensitivity, however, depends upon the type of structure, the material strain hardening properties, the type of loading, and the level of loading. An assessment of these effects and some guidance on the conditions where they are significant were accomplished. (ERA citation 12:038868)
