Figure 5: The effect of external body force on the displacement
It is evident from Figs. 4(a-c) that the existence of the external body
force has a clear effect on temperature, displacement, and stress. Also,
we observe that the values of the physical quantities converge to zero
at \(x\) tends to 4, which is in quite good agreement with the
regularity boundary conditions. From all the figures, it is obvious that
the absolute of the external body force increases the amplitudes of all
studied fields.
