Topology optimization of eigenvalues for elastic structures by topological derivatives and time domain response

This paper derives the topological derivative of structural eigenvalues based on the partial differential equations of time-harmonic elastodynamics and their weak form, with the goal of achieving topology optimization of structural eigenvalues. To compute the topological derivative, it is first nece...
