Linear coefficient of thermal expansion steel
Did you know?
NettetCoefficient Of Linear Thermal Expansion (CLTE, α L) This is a fixed value which is used to determine how much a small change in temperature will affect the length of a particular substance. The coefficient defines the fractional change in length of a substance per unit change in its temperature. Start Length (L 0) When calculating thermal expansion it is necessary to consider whether the body is free to expand or is constrained. If the body is free to expand, the expansion or strain resulting from an increase in temperature can be simply calculated by using the applicable coefficient of thermal expansion. If the body is constrained so that it cannot expand, then internal stress will be …
