- N-Value - AHSS Guidelines
The n-value determines the allowable biaxial stretch within the stamping as defined by the forming limit curve (FLC) The traditional n-value measurements over the strain range of 10% – 20% would show no difference between the DP 350 600 and HSLA 350 450 steels in Figure 2
- Manning’s Roughness Coefficients for Open Channel Flow
Manning's roughness coefficients for some common materials The Manning's roughness coefficient is used in the Manning's equation to calculate flow in open channels Coefficients for some commonly used surface materials:
- Metal Properties: Strain-Hardening Exponent (n-Value)
ASTM E646, Standard Test Method for Tensile Strain-Hardening Exponents (n -Values) of Metallic Sheet Materials, describes the steps required to calculate n-value from tensile-test data
- Mannings Roughness Coefficient - United States Army
HECRAS uses Manning's equation to compute friction losses in the culvert barrel, as described in the section entitled "Culvert Hydraulics" of this chapter Suggested values for Manning's n
- What is N-value? - Instron
n-value, also known as the strain hardening exponent, is the measure of a metal’s response to cold working Cold working is the plastic deformation of metal below its recrystallization temperature and this is used in many manufacturing processes, such as wire drawing, forging and rolling

- ISO 10275: Calculation of n-value hardening exponent
The n -value can be calculated from the raw data (force and extension) of the tensile test (e g to EN 10002-1, ISO 6892, ASTM E8) with direct strain measurement
