SUMMARY
The discussion centers on the behavior of ANSYS during non-linear analysis with multilinear isotropic hardening, specifically regarding the extrapolation of maximum principal stress values beyond the input limits. User Earth_2304 confirms that this extrapolation indicates that the part is overstressed, suggesting that the model may require adjustments to avoid exceeding permissible stress levels. This behavior is a common occurrence in finite element analysis when material properties are not adequately defined or when the loading conditions lead to unexpected results.
PREREQUISITES
- Understanding of ANSYS software, particularly its non-linear analysis capabilities.
