Calculating Elastic Plastic Strains Using Ansys nCode DesignLife Software — Lesson 1

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.

1. You must run an FE analysis using elastic-plastic material properties.
2. 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.
3. You must deactivate the elastic-plastic correction. By default, nCode DesignLife software invokes the elastic-plastic correction.
