linearExpansionPercent(Tk=None, Tc=None)

return linear expansion in %dL/L from interpolation of tabular data.

This function is used to expand a material from its reference temperature (21C) to a particular hot temperature.

Parameters

• Tk (float) – temperature in K

• Tc (float) – temperature in C
