Abstract
Composite laminate are widely used in different industries as aerospace, naval and automobile. Developing accurate models in order to represent manufactured components is necessary to aid the design of structural health monitoring (SHM) systems. In addition, the most part of the SHM strategies consists on compare the intact state with the damaged state to obtain a damage index. In this context, this work presents a model updating strategy to obtain the input parameters used in a Finite Element Method (FEM), which represent the experimental dynamic behavior of a composite plate. For this, a Kriging metamodel is chosen to reduce the computational cost of optimization process into the model update. A set of finite element analyses are used to training the metamodel. After that, the kriging model is used every time when the objective function is evaluated. This strategy provides a considerable reduction in the computational time during the optimization process, where for this paper a PSO are going to be used. These results are analyzed in order to evaluate the potentialities and limitations of the methodology. Therefore, the strategy presented can be helpful in the study of damage detection systems that uses FEM as part of its process.
