The coefficient of expansion is the ratio of the change in length or volume of a body to the original length or volume for a unit change in temperature.
Unit increase in size resulting from a unit increase in temperature; measured in inches per inch per degree Fahrenheit (in/in/1/2°F) or in millimeter per millimeter per degree Celsius (mm/mm/1/2°C).
The ratio of change in length, area, or volume per degree to the corresponding value at a standard temperature.
of Steel A factor applied to steel to quantify the effects of temperature on its expansion. Its value is 0.000012 / 'c.
The value of the ratio of the dimensional change (length, area, volume) of a material to the change in temperature that has caused it.
the fractional change in length or area or volume per unit change in temperature at a given constant pressure
The characteristic rate of expansion of a substance resulting from increased molecular vibration as the temperature increases, or of shrinkage from decreased vibration as the temperature falls.
A change in length, area or volume given a degree change in temperature.
A measure of the change in length or volume of an object.
The rate of change in the size or length of a building component or a measuring tape caused by a given change in temperature. A steel building 200' long without expansion joints will be 5/8 inch bigger at 75 degrees farenheit than it is at 35 degrees. A steel measuring tape likewise changes length with temperature change, but a LDM does not.
a measure of the degree to which a compound grows in size as its temperature is increased; elastomers have higher coefficients of expansion than do metals, which leads to differences between the room temperature dimensions of a mold and the room temperature dimensions of a rubber part made from that mold (see shrinkage)
The measured expansion of heated glass based on the percentage of change of a glass rod heated one degree centigrade.
The fractional change in length (sometimes volume, specified) of a material for a unit change in temperature. Values for plastics range from 0.01 to 0.2 mils/in., C.
The coefficient of linear expansion is the ratio of the change in length per degree to the length at 0°C.
A measurement of how much a glass expands or contracts in length per degree of temperature, expressed in meters per degree Celsius. The typical COE of borosilicate glasses are 30 to 34 x 10-7 m/°C, where soda-lime glasses tend to have expansions in the 90 to 100 x 10-7 m/°C range. See COE for other known acronyms.
