Sensor placement for structural damage identification by means of topology optimization

Identifying critical and vulnerable links: A new approach using the Fisher information matrix

“…More recently, in [59], a method of multi-objective sensor locations optimization using the collected information by FIM is presented. In this study, the sensor locations are prioritized according to their ability to localize structural damage based on the eigenvector sensitivity method, and in the same area, a method based on the FIM matrix and the structural topology optimization concept to establish a methodology for the optimal placement of sensor for structural damage identification is presented by [60].…”

Optimal sensor placements using modified Fisher information matrix and effective information algorithm

“…Jiang et al 8 investigated the effect of different weighting coefficients on the maximization of the FIM using a mathematical property of the product of the target mode and its transpose and an alternative EI formula. Blachowski et al 9 established an OSP method based on the FIM matrix and the structural topology optimization concept to convert a discrete optimization problem into a continuous problem. He et al 10 introduced the generalized equivalent stiffness and importance coefficient of the component and used statistical data to obtain a sensor placement structure.…”

Merging experimental design and structural identification around the concept of modified Constitutive Relation Error in low-frequency dynamics for enhanced structural monitoring

“…Among many contributions, let us mention [29,30] that use genetic algorithms to optimally position sensors for damage detection. Of course, other metaheuristic techniques can be used for sensor placement such as neural networks [31,32], topology optimization-inspired algorithms [33,34], simulated annealing [31,35] or mixed variable programming [36]. A comprehensive review of these techniques is given in [15].…”
