Abstract

At this stage we return to the full thermoelastic equations (1.1.1) and (1.1.2), that is to say to the equations
$$ \begin{gathered} \frac{{{\partial^2}\theta }}{{\partial {x^2}}} = \frac{{\partial \theta }}{{\partial t}} + \sqrt {a} \cdot \frac{{{\partial^2}u}}{{\partial x\,\partial t'}} \hfill \\ \frac{{{\partial^2}u}}{{\partial {x^2}}} = \sqrt {a} \cdot \frac{{\partial \theta }}{{\partial x\,}} + b\frac{{{\partial^2}u}}{{\partial {t^{{2'}}}}} \hfill \\ \end{gathered} $$
in which the inertial term b∂2u/∂t2 is retained: we suppose, as before, that the faces of the body are clamped and, therefore, that
$$ u{\left| {_{{x = 0}} = u} \right|_{{x = 0}}} = 0 $$
These are our original boundary conditions (1.1.3).
