- In this paper, we extend our research concerning the standard and linearized monotonicity methods for the inverse problem of the time harmonic elastic wave equation and introduce the modification of these methods for noisy data. In more detail, the methods must provide consistent results when using noisy data in order to be able to perform simulations with real world data, e.g., laboratory data. We therefore consider the disturbed Neumann-to-Dirichlet operator and modify the bound of the eigenvalues in the monotonicity tests for reconstructing unknown inclusions with noisy data. In doing so, we show that there exists a noise level $δ_0$ so that the inclusions are detected and their shape is reconstructed for all noise levels $δ< δ_0$. Finally, we present some numerical simulations based on noisy data.
