polyfitLinearExpansionPercent(power=2)[source]¶

Calculates the coefficients of a polynomial fit for linearExpansionPercent. Based on data from http://www.specialmetals.com/documents/Inconel%20alloy%20X-750.pdf

Uses mean CTE values to find percent thermal strain values. Fits a polynomial to the data set and returns the coefficients.

Parameters: power (int, optional) – power of the polynomial fit equation
Return type: list of length ‘power’ containing the polynomial fit coefficients for linearExpansionPercent

linearExpansionPercent(Tk=None, Tc=None)[source]¶

Returns percent linear expansion of InconelX750.

Parameters

Tk (float) – temperature in (K)
Tc (float) – Temperature in (C)

Return type

linExpPercent in %-m/m/C

linearExpansion(Tk=None, Tc=None)[source]¶

From http://www.specialmetals.com/documents/Inconel%20alloy%20X-750.pdf

Using the correlation for linearExpansionPercent, the 2nd order polynomial is divided by 100 to convert from percent strain to strain, then differentiated with respect to temperature to find the correlation for instantaneous linear expansion.

i.e. for a linearExpansionPercent correlation of a*Tc**2 + b*Tc + c, the linearExpansion correlation is 2*a/100*Tc + b/100

2*(6.8378e-7/100.0)*Tc + 1.056e-3/100.0

Parameters

Tk (float) – temperature in (K)
Tc (float) – Temperature in (C)

Return type

linExp in m/m/C
