You mean that the temperature is given ?
Could you write down the expression of the term which takes into account the 
thermal expansion (I am not a specialist). If it is a supplementary term in 
the equation compared to the standard linearize elasticity, it should be 
possible to build a brick which modify the linearized elasticity brick adding 
a term in the stiffness matrix.
