Web8 nov. 2024 · Linear Expansion. The end result of this is that (for reasonably low temperature changes) the percentage expansion/contraction of the length of an object is proportional to the temperature change: (5.2.2) Δ L L o = α Δ T. The constant α is called the coefficient of linear expansion, and it has units of K − 1 (or, equivalently, o C − 1 ). Webthe volume coefficient of thermal expansion. In many materials, the value of α V is anisotropic; that is, it depends on the crystallographic direc-tion along which it is measured. For materials in which the thermal expansion is isotropic, α V is approximately 3α 1. Measurement To determine the thermal expansion coeffi-
