Damage identification in a concrete beam using curvature difference ratio [PDF]
, 2011 Previous studies utilising changes in mode shape or curvature to locate damage rely on the fact that the greatest change occurs around the defect. However, in concrete beams this fact is undermined due to the nature of the defect as distributed multi ...

MONITORING AND IDENTIFICATION OF STRUCTURAL DAMAGES
Mechanika, 2011 This paper presents the investigation of structural damage identification methods based on results of numerical modeling and deformation monitoring. Solution of deformed body mechanics task by contradiction describing the structure mechanical condition according to its loading and deformation nature is proposed.

Numerical Simulation-Based Damage Identification in Concrete [PDF]
Modelling, 2021 High costs for the repair of concrete structures can be prevented if damage at an early stage of degradation is detected and precautionary maintenance measures are applied. To this end, we use numerical wave propagation simulations to identify simulated damage in concrete using convolutional neural networks.

Perturbation damage indicators based on complex modes [PDF]
, 2017 The papers focusing on dynamic identification of structural damages usually rely on the comparison of two or more responses of the structure; the measure of damage is related to the differences of the vibration signals.
