2. Physical and mathematical models

Calculating the vibratory response of an immersed structure involves solving a matrix problem of the following form:

( 1 )

The matrix equation is obtained using an appropriate numerical method – typically the finite element method – and adapted to the equations describing the vibratory dynamics of the system; on modeling assumptions, finite element approximation methods and the various...
