It then follows from (4.56) and (4.60) that for any values of the parameters ε, σT and ΔT
Clearly the following relations must be satisfied
On using (4.1), these relations are now expressed as
It should be noted that the quantity αT+νAαA is the transverse thermal expansion coefficient for plane strain conditions such that uz=0. On using (
