Strain Life

The strain life material option specifies the fatigue strain life parameters determined from uniaxial strain life tests.

Parameter Description
Ef' Fatigue ductility coefficient
c Coffin-Manson fatigue ductility exponent
Sf' Fatigue strength coefficient
b Basquin's fatigue strength exponent
Knee Life (2Nf) for b2 Knee in life curve (life above which to use b2)
b2 Basquin's fatigue strength exponent at lives above the knee in life curve
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.
