In a strain life (EN) fatigue analysis using Ansys nCode DesignLife software, is it possible to use elastic-plastic strains calculated directly in the finite element (FE) analysis?
Yes, but you must take the following actions.
- You must run an FE analysis using elastic-plastic material properties.
- You must instruct nCode DesignLife software to import the full stress-strain field (both stress and strain results) from the results file. By default, nCode DesignLife software only imports elastic stresses. It then calculates plastic strains using an elastic-plastic correction.
- You must deactivate the elastic-plastic correction. By default, nCode DesignLife software invokes the elastic-plastic correction.
