In most applications the second-order equation looks like Mu00+Ku = 0, with a mass
Chapter 5, Problem 5.4.16(choose chapter or problem)
In most applications the second-order equation looks like Mu00+Ku = 0, with a mass matrix multiplying the second derivatives. Substitute the pure exponential u = e it x and find the generalized eigenvalue problem that must be solved for the frequency and the vector x.
