The operator interpretation of the given boundary value problem is investigated in the Hilbert space H = L2,ρ 0, ∞; C 2 × C. The resolvent operator is constructed and the expansion formula with respect to eigenfunctions is obtained. Copyright c 2009 Yang's Scientific Research Institute, ...
The coefficient of linear thermal expansion formula is thus given by {eq}\alpha =\frac{\Delta L}{L\Delta T} {/eq} Similar to the equation for the linear expansion coefficient, the equations for the superficial and volume expansion coefficients are given by the following: ...
Thermal expansion coefficient refers to the extent to which the size and volume of materials change with temperature. It is an important parameter for material application and structural design, and is related to thermal shock resistance, stress distribution, and size changes after heating. ...
The expansion coefficient is a parameter indicating such property. Usually, the expansion coefficient refers to length variation of a material per unit length under temperature variation by 1K, so it is also called the linear expansion coefficient (1/K) to be distinguished from the volume expansion...
