Unidirectional Composite Wide Beam, Identification, Impact Location, Impact Force Reconstruction.


Reconstruction of the impact force history and identification of the impact location are important tasks in structural health monitoring (SHM) applications, namely in case of composite structures. These tasks are critical especially in cases, when it is not possible to measure the impact force directly and the knowledge of the intensity and position of loading force is necessary for the damage prediction of the structure. This paper tests two methods for the reconstruction of impact force and identification of impact location. The first method uses finite element analysis (FEA) for determination of a transfer matrix of a system. The second method uses experimental results only. The methods are tested on an orthotropic prismatic wide beam with rectangular cross-section. Three piezoelectric patch transducers are bonded to the beam bottom-surface to measure deformations.
