The distributions of stress and displacement components on different (longitudinal and transverse) cross-sections are discussed. Results show that the distribution of bending normal stress on two clamped sides is different from one on other transverse cross-sections. The bending normal stress varies on the fixed sides in a robustly nonlinear fashion. It changes within most range of other transverse cross sections in a linear way while it varies in the vicinity of interface between two materials in a slowly nonlinear way. There is only one neutral axis on the fixed sides and the other transverse cross sections, which resides in the same location inside the material with bigger stiff- ness.
