If you are calculating the change in area rather than length, multiply the increase in length by two to find the area increase. Example problems A steel bar with a cross-sectional area of 2 cm 2 is heated, raising its temperature by 120 o C and prevented from expanding. Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.. The thermal expansion coefficient represents the amount that the material expands per each degree increase. The expansion of alcohol in a thermometer is one of many commonly encountered examples of thermal expansion, the change in size or volume of a given mass with temperature.Hot air rises because its volume increases, which causes the hot air’s density to be smaller than the density of surrounding air, causing a buoyant (upward) force on the hot air. Thermal expansion is given in terms of thermal expansivity (a = 1/L (dL/dT), or more usefully for most applications, in terms of the integrated expansion (or contraction) between two temperatures. It can also be used to automatically close or open a switch at a certain temperature, as in older or analog thermostats. The thermal expansion coefficient represents the amount that the material expands per each degree increase. Melting point of high-carbon steel is around 1515°C. The volumetric thermal expansion coefficient is probably the most basic thermal expansion coefficient, and probably the most related for fluids. The expansion of alcohol in a thermometer is one of many commonly encountered examples of thermal expansion, which is the change in size or volume of a given system as its temperature changes.

The temperature dependent material properties for the strucural solver, like thermal expansion coefficient, are defined with *MAT_ADD_THERMAL_EXPANSION. Thermal expansion can also be regarded as a fractional change in size of a material/substance caused by a change of temperature. The most common method is the inclusion of expansion elbows, loops, or z-bends. Like most materials, steel expands when the surrounding temperature increases. The effect in cryogenic systems is significant; a typical value for austenitic stainless steel is 3 mm of contraction per meter between 300K and 4K. Different materials have different CTEs, which make them suited for the particular use they are selected for. Coefficient of thermal expansion must be considered in components that use a mixture of materials such as heat exchangers with mild steel shells and austenitic grade tubes. Understanding the relative expansion/contraction characteristics of materials is important for application success. According to EN1991-1-3 §3.2.6, for calculating the structural effects of unequal temperatures in composite concrete-steel structures to EN 1994 the coefficient of linear thermal expansion may be taken as α = 10 ×10 -6 °K -1, i.e. The thermal expansion of concrete may be calculated according to ENV-1994-1-2 [3] as: 3 i 11 i 4 6 th ,i / 1.8 10 9.0 10 2.3. CTE is used for design purposes to determine if failure by thermal stress may occur. Thermal expansion is normally calculated in two ways, as a linear (single dimension) or volumetric (3 dimensional) measurement. Thermal expansion – problems and solutions. Assuming that the initial area is equal with the square of the initial length: equation (8) becomes (6). How the Thermal Expansion Coefficient Table works?
