2. Systems with N degrees of freedom
The behavior of self-joining, conservative mechanical structures can be represented by the following matrix equation:
( 2 )
M represents the mass matrix, real, symmetrical, positive definite*, K the stiffness matrix, real, symmetrical, non-negative definite**. Both matrices are of dimension (N,N).
f (t) represents the vector of exciting forces. In the harmonic...
