AbstractThe article describes a test procedure based on the fundamental principle of Nonlinear Elastic Wave Spectroscopy. Without integration of all test stages into one automated measurement station and without Maximum Length Sequence (MLS) perturbation signal, this method would be otherwise lengthy and unfit for practical application. Material nonlinearities are elegantly quantified in a single coefficient. Furthermore, in the same measurement Eigenfrequency of the sample can be estimated with greater accuracy than in conventional methods. The method is applied on thermally loaded mortar samples
