In this paper, first, the concept of hybrid method is presented. On the basis of this concept, various hybrid experimental methods are classified into five categories: (i) hybrid experimental-numerical method, (ii) hybrid numerical-experimental method, (iii) hybrid anal ytical-experimental method, (iv) hybrid experimentalanalytical method, and (v) hybrid experimental-experimental method. Among them, the focus is put in the hybrid experimental-numerical method, which hybridizes an experimental method and a numerical method. The hybrid experimental-numerical method can achieve a new ability that cannot be obtained by the experimental method alone. The effectiveness and usefulness of various hybrid experiment-numerical methods are explained by using the results obtained by our recent studies. Especially, the power was demonstrated for the developments of intelligent hybrid measurement methods and dynamic fracture-path prediction methods.
