Abstract
Notches are
the stress raiser regions. Along the notch section, not only the stress distribution
becomes non-uniform, but also the stress level reaches the maximum value. These
geometrical disorders can be undesirable such as casting cavity but sometimes
these disorders are created deliberately for assembly process such as keyway
holes or shaft steps. Because of the necessity of these notches. This is
important to understand material behavior along this region.
In this study,
three different strain paths were generated by the cyclic tensile and torsional
loadings and strains of the notch root of a shaft which contains
circumferential notch, were investigated through the finite element method
(FEM). MSC. Marc commercial program have been used in this study as finite
element software. The results have been obtained for kinematic hardening rules
and compared with the experimental results obtained from literature studies.
Also in this study, a subroutine file was used to calculate the Chaboche
kinematic hardening rule parameters according to Swift equation.
