nLet's say the CTE is 0.001/C and consider a 100 mm long piece of material and 23 C is the reference/environment temperature.nSet the temperature to 20C, which is a -3C change so the part shrinks by 0.3 mm.nSet the temperature to -35C, which is a -58C change so the part shrinks by 5.8 mmnThe deformation at -35C is larger than the deformation at 20C. This is the expected behavior.nn
