Surface waves of large amplitude beneath an elastic sheet. part 2. galerkin solution

摘要: This study continues the work of Forbes (1986) on periodic waves beneath an elastic sheet floating surface infinitely deep fluid. The solution is sought as a Fourier series with coefficients that are computed numerically. Waves extremely large amplitude found to exist, and results presented for belonging several different nonlinear branches, characterized by numbers inflexion points in wave profiles. existence multiple solutions, conjectured previous paper (Forbes 1986), confirmed here direct numerical computation.
