Localization of damage in a system is an issue that has been widely studied in structural health monitoring. The Dynamic Damage Locating Vector (DDLV) method localizes damage from information in the null space of the change in transfer matrices (ΔG). A precisely known ΔG and an accurate model of the reference state represent ideal conditions in the DDLV approach. Since ideal conditions are not realized in practice, the question of robustness arises. This paper examines the performance of the DDLV approach under error in ΔG coming from truncation of the modes to a limited bandwidth. The numerical results are obtained using a rectangular thin plate model.
