【Abstract】

<正>Design of band-gap structures receives increasing attention for many applications in mitigation of undesirable vibration and noise emission.The aim of this paper is,by way of gradient-based shape optimization,to maximize band-gaps of transversely vibrating Bernoulli-Euler beams subjected to free,standing wave vibration, or forced,time-harmonic wave propagation.The beams are
