9.5 The following thermal bimorph is made of Silicon with a thermal conductivity
k = 130 W/(m°C), Young's modulus E = 200 GPa, Poisson's ratio v = 0.27, and ther-
mal expansion coefficient a = 2.6 × 10-6/°C. It is 1 mm thick with fixed tempera-
tures of 60°C and 10°C, respectively, at the leftmost ends of its hot arm and cold
arm, as shown below. Suppose the bimorph has a uniform internal heat genera-
tion at 100 W/m³, and ignore the effects of convective heat transfer. (1) Determine
the steady-state temperature distribution in the thermal bimorph. (2) Determine
the thermally induced deformation and stresses in the bimorph if the two arms
are fixed on their left ends.
Hot arm
Thot = 60°C
Cold arm
