AbstractStructural damage identification is a key issue for several sectors, and the damage issue can be formulated as a class of inverse vibration problem. This inverse problem can be formulated as a generalized least square problem. The stiffness matrix is the goal for the identification process, where the measurements are the reference for the best matching with a mathematical model associated with a regularization operator. The forward problem is solved by the finite element method, and an entropic regularization is also used for the cost function. Here, two types of inverse methods will be applied. An inverse solution is estimated by combining a stochastic metaheuristic (MPCA: multi-particle collision algorithm) with a local searching method (HJ: Hooke-Jeeves) [1], and a second technique employing a variational approach [2]. The proposed methodologies are applied to different study cases: the cantilever beam and space truss structure, the last one as a simplified representation of the International Space Station (ISS).
