Test Case
A beam of length 
and width w made up of two layers
of different materials is subjected to a uniform rise in temperature
from Tref to To, and
a bending moment My at the free-end. Ei and α
i correspond to the Young's modulus and thermal
coefficient of expansion for layer i, respectively.
Determine the free-end displacement δ (in the Z-direction) and the X-direction stresses at the top and bottom surfaces of the layered beam.
This problem is also presented in VM144
in the Mechanical APDL Verification Manual.
