The assembly consists of a brass shell (1) fully bonded to a solid ceramic core (2).
The brass shell [E = 115 GPa, a = 18.7 × 10-6/°C] has dout 50mm. and din
= 35mm.
The ceramic core [E = 290 GPa, α = 3.1 x 10-6/°C] has a diameter dout = 35mm.
At a temperature of 15°C, the assembly is unstressed. AT = 60°C.
Find the internal stress in the brass.
