Approximate analytical solutions for the steady?state oscillations are presented for the fundamental mode, for the first and second subharmonics, and for the first and second harmonics to second order in the expansion. These results are compared with some numerical ones and a very good agreement is found.en-USViscous liquidAsysmptotic analysisarticle
