The problem is solved by minimizing a functional depending on the eigenvalues and traces of corresponding eigenmodes. We use the adjoint method to calculate the shape derivative of this functional. The optimization is performed by BFGS, using a genetic algorithm as a preprocessor and the Method of Fundamental Solutions as a solver for the direct problem. We address several numerical simulations that illustrate the good performance of the method.engInverse problemShape optimizationEigenvalue problemLinear elasticityAdjoint methodMethod of fundamental solutionsDetection of holes in an elastic body based on eigenvalues and traces of eigenmodesjournal article
