    MODEL PEMBENTUKAN FENOMEA LAYANGAN PADA GELOMBANG DUA DIMENSI
    (Elfitra, 2022-01) Safariayah, Dyah Tri; Defrianto, Defrianto
    Research has been carried out to model the formation of the beats phenomenon on twodimensional waves using the finite element method of computation. The beats formation modeling is carried out using a PC (personal computer) that has been installed with Matlab R2016a application. The beats is modeled using a circular domain bounded by a barrier with shape triangle and square in the middle of the circle. Each domain is assigned the same frequency, for the first frequency (f1) used is 150 Hz, and 450 Hz. For the second frequency (f2) is 155 Hz and 455 Hz. The x values used are x=4 and x=8, while the y values used are y=14. Based on all the research results, the beats will form a pattern of valleys and wave crests. The maximum amplitudo given a barrier with shape triangle is 0,5. And the maximum amplitudo given barrier with square is 0,35.
