“…This method is more often used considering only the first mode, i.e., N modes ¼ 1. The method frequently gives additional, false peaks and it is not widely used for real applications (Manoach et al 2016a).…”

This chapter aimed to present different data driven Vibration-Based Methods (VBMs) for Structural Health Monitoring (SHM). This family of methods, widely used for engineering applications, present several advantages for damage identification applications. First, VBMs provide continuous information on the health state of the structure at a global level without the need to access the damaged elements and to know their location. Furthermore, damage can be identified using the dynamic response of the structure measured by sensors non-necessarily located in the proximity of damage and without any prior knowledge about the damage location. By principle, VBMs can identify damage related to changes in the dynamic properties of structures, such as stiffness variations due to modifications in the connections between structural elements, or changes in geometric and material properties. A classification of different VBMs was presented in this chapter. Furthermore, several case studies were presented to demonstrate the potential of these methods.

“…Hu et al (1999) suggested artificial springs to model the contact forces between delaminated segments based on Midlin plate theory in the buckling behavior of laminate structures. Manoach et al (2016) investigated the effect of large deflections and evaluated temperature on the vibration of delaminated Timoshenko composite beam. In this study, damping due to the interaction of sub-laminates was discussed in detail.…”

The main aim of this paper is to study the non-linear vibration of a delaminated cross-ply composite beam with two overlapping delaminations. The effect of geometrical non-linearity and large deflection on the axial forces due to the existence of two overlapping delaminations are considered. The unknown axial forces created due to the delaminations are obtained by changing the length of the delaminated segments during the vibration behavior. The homotopy perturbation method (HPM) is utilized to obtain the frequency ratio of the delaminated cross-ply composite beam with two overlapping delaminations. This study describes the effects of different parameters such as two delaminations total length, overlap distance, and the distance between center points of two delaminations in axial and thickness directions on the frequency ratio of the delaminated composite beam in detail.
