The occurrence of subharmonic tones in a beam supported by springs and dampers at both ends, and subjected to a nonsymmetric excitation having two components, one independent of, and the other harmonically varying with, time is considered. The beam can form a system with internal resonance due to the size of spring constants of support ends. To analyze the problem, the method of multiple scales is used. The analysis shows that in the system with internal resonance considered here, subharmonic tones of orders 1/2 and 1/3 can occur in a multi mode. The validity of the theoretical analysis is confirmed by numerical simulation.
