Fatigue calculations

Simulation Generality
1

Hello
Fatigue calculations are *usually* based on either the PRINCIPAL stresses or the stress INTENSITY (maximum absolute normal stress (P3) - minimum absolute normal stress (P1)). 
Our subcontractor is working on Abaqus and is interested in "Stress range, Max. Main" to ensure that standards are met.
My question: What is the "Stress range, Max. Main" visualized on Abaqus? Otherwise, I'm looking to visualize the stress profile on SolidWorks, which is roughly equal to "Stress range, Max. Principal" examined on Abaqus?  Is it really the INT (Stress INTENSITY) component?

Thank you!

Hello

In Simulation, you can define the stress component to calculate the alternating stress: the stress intensity (P1 - P3), the equivalent stress (von Mises), or the maximum absolute principal stress (P1). (source help Solidworks)
