Life estimation by varying the critical plane orientation in the modified Carpinteri-Spagnoli criterion
The modified Carpinteri-Spagnoli (C-S) criterion is a multiaxial high-cycle fatigue criterion based on the critical plane approach. According to such a criterion, the orientation of the critical plane is linked to both the averaged directions of the principal stress axes and the fatigue properties...

| description | The modified Carpinteri-Spagnoli (C-S) criterion is a multiaxial high-cycle fatigue criterion based on
the critical plane approach. According to such a criterion, the orientation of the critical plane is linked to both
the averaged directions of the principal stress axes and the fatigue properties of the material. The latter
dependence is taken into account through a rotational angle, . Then, the multiaxial fatigue strength estimation
is performed by computing an equivalent stress amplitude on the critical plane. In the present paper, some
modifications of the original expression are implemented in the modified C-S criterion. More precisely, such
modified expressions of depend on the ratio between the fatigue limit under fully reversed shear stress and
that under fully reversed normal stress (in accordance with the original expression), and can be employed for
metals ranging from mild to very hard fatigue behaviour. Some experimental data available in the literature are
compared with the theoretical results in order to verify if the modified expressions are able to improve the
fatigue strength estimation capability of the modified C-S criterion |
