How plastic strain per cycle in fatigue is increases how it will be solve using ansys for constant amplitude loading?
That's interesting. How does the strain-life approach work?
The strain-life approach works by plotting the applied stress amplitude against the number of cycles to failure. This is done by first determining the strain-life curve for the material being tested, and then equating the plastic strain amplitude to the applied stress amplitude. ANSYS can then use this curve to predict the number of cycles to failure for a given stress amplitude.
