Abstract: The computational problems associated with the estimation of damping, particularly in piping systems, is discussed in detail and appropriate procedures are recommended to minimize their impact. ...

Abstract: A self-starting multistage, time-domain procedure is presented for the identification of nonlinear, multi-degree-of-freedom systems undergoing free oscillations or subjected to arbitrary direct force ...

Abstract: A time-domain procedure for the identification of nonlinear vibrating structures, presented in a companion paper, is applied to a “calibration” problem which incorporates realistic test situations ...
