The first two items in *Macromechanics* are *Laminate Density *
and *Laminate coefficient of thermal expansion *(CTE)
. The density is calculated as the weighted average of the densities of the laminas in the laminate. The CTE are the strains caused by a unit change of temperature. CADEC calculates the thermal loads caused by a unit change of temperature, then uses those loads to compute the strains and thus the CTE.
