Description Parameter
Specify the thickness of the reduced
cross-sectional area on the specimen. Thickness -
Rectangular
Specimens
Thickness is a specimen variable that other
variables may use in a calculation.
Specify the length on the specimen that has the
reduced cross-sectional area. Extensometer Gage
Length (L)
Extensometer Gage Length is a specimen variable
that other variables may use in a calculation.
The value you specify here represents the slope
value of the material’s stress-strain curve in the
elastic deformation region. Elastic Modulus (E)
Elastic Modulus is a specimen variable that other
variables may use in a calculation.
Specify the stress value at which permanent
deformation occurs. Yield Strength
Yield Strength is a specimen variable that other
variables may use in a calculation.
Specify the temperature at which Elastic Modulus
and Yield Strength are valid. Valid at Temperature
