Abstract
The periods of the periodic travelling wave solutions for an elastic beam equation were studied. By the transformation of variables, the elastic beam equation was reduced to a planar differential system. The period function of the planar differential system is examined. It was proved that the period function is a monotonic function. Moreover, the asymptotic behaviour of the period function was also given.
