Abstract : The Timoshenko theory of flexural vibrations of beams and the WKB method are adopted to evaluate the amplitude changes of the free vibrations of beams, the length of which varies linearly with time. It is found that the change is dependent only on the length increase (or decrease). Results are also given for the frequency modifications. (Author)
