Kriging Surrogate Models for Predicting the Complex Eigenvalues of Mechanical Systems Subjected to Friction-Induced Vibration

Table 13

Comparison of the number of samples for each of the case studies and (i.e., for 2 or 3 parameters) in order to compute the deterministic results via CEA or to construct a kriging metamodel.
