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.
