Detailed Description

Material designed to provide a time-invariant volumetric thermal expansion coefficient A = * (alpha - phi) * alT + phi * alF .

Here alpha = Biot coefficient (assumed constant) phi = initial value of porosity alT = drained volumetric thermal expansion coefficient (assumed constant) alF = fluid volumetric thermal expansion coefficient (assumed constant)
