ST7-1.30.20.3 Nonlinear Thermal Expansion
Strand7 allows for the continuous variation of coefficient of thermal expansion with respect to changing temperature. The variability of the coefficient can be expressed in various ways, including thermal strain vs temperature, as the average coefficient over a range of temperatures, or as an instantaneous coefficient which must be integrated to get the total thermal strain. This Webnote outlines how to use Strand7 to model nonlinear variations of thermal expansion coefficient with respect to temperature.
