With the cross-sectional area function as the design variable, we seek the optimum design of clamped–clamped, thin, linearly elastic beam-columns under thermal load that maximizes the buckling temperature or the fundamental natural frequency of tra

Optimum design of band-gap beam structures

Autor: Niels Olhoff, Bin Niu, Gengdong Cheng

Publikováno v: Olhoff, N, Niu, B & Cheng, G 2012, ' Optimum design of band-gap beam structures ', International Journal of Solids and Structures, vol. 49, no. 22, pp. 3158-3169 . https://doi.org/10.1016/j.ijsolstr.2012.06.014

The design of band-gap structures receives increasing attention for many applications in mitigation of undesirable vibration and noise emission levels. A band-gap structure usually consists of a periodic distribution of elastic materials or segments,
