Relation between the results of a bending test and the critical deformation of the tested metal
https://doi.org/10.22349/1994-6716-2022-112-4-83-93
Abstract
The features of sample deformation during bending tests using numerical methods of investigation – FEM are considered. Formulas are presented for determining the critical deformation of a metal based on the results of a bending test. With formulas, it is possible to predict the minimum diameter of the mandrel, which provides a satisfactory result, depending on the ability of the material to work hardening.
