摘要
This paper presents a new method for the damage localization and severity estimate for lattice material based on substructure modal energy. The significant advantage associated with new method over traditional modal energy methods is that the spatially complete mode shape isn't needed. Additionally, the new method does not require the analytical and measured modes to be consistent in scale, or to be normalized. Numerical studies in this paper are conducted for lattice material based on synthetic data generated from finite element models.
