Stress Life

The stress life material option specifies the uniaxial S-N and/or shear stress versus N curve.

Parameter Description
S Amplitude Uniaxial stress amplitude.
Shear Amplitude Shear stress amplitude.
Nf Number of cycles to failure.
Use R-Ratio dependent data (Applies to S-N curve only.) Adds dependence on R-ratio measure for the relative mean stress.
Use temperature-dependent data Specifies material parameters that depend on temperature. A Temperature field appears in the data table. For more information, see Specifying Material Data as a Function of Temperature and Independent Field Variables.
