TL;DR: In this paper, an analytical model is developed from crash test measurements using system identification techniques, which is made up of two parts: a differential equation part consisting of mass, stiffness and damping characteristics, and a transfer function part, consisting of an autoregressive moving average (ARMA) of white noise.

Representation of Damping Matrix
TL;DR: In this paper, a matrix representation based on a theorem of matrix representation that, under certain circumstance (which can be easily checked), a matrix C can be represented accurately by a polynomial of two given matrices M and K is presented.
