Temperature_Factor
Temperature_Factor(T)
Function Temperature_Factor returns the temperature modification factor (The Marin factor k_d). This function is meant to modify the endurance limit for temperature effects in situations where the temperature dependent ultimate strength is not known. It is valid for steels over a range from 20 C < T < 500 C.
Input:
T = temperature ([C], [K], [R], or [F])
Output:
Returns the dimensionless temperature modification factor.
Example:
$Load Mechanical Design
$UnitSystem SI Mass J C Pa
k_d=temperature_factor(200 [C])
{Solution:
k_d = 1.024}
