“…Recently, Amabili [1,2], Amabili et al [3], Gonialves and Ramos [4], Chiba [5,6] and Chiba and Osumi [7] have studied vibration of plates, shells and plate}shell systems coupled with sloshing, quiescent and inviscid #uid by inserting the sloshing condition into the eigenvalue problem. This is an interesting semi-analytical approach that allows avoiding the closed-form solution of the velocity potential of sloshing liquid by inserting it into an eigenvalue problem of enlarged dimension.…”
