Assessment of Vibration-based Damage Identification Methods Using Displacement and Distributed Strain Measurements (2009, background): “This is because modal curvatures obtained through numerical differentiation of ‘noisy’ mode shapes are vulnerable to additional error for smaller sampling intervals (more sampling points), while larger sampling intervals (less sampling points) cause truncation error [6].”
A new technique to optimize the use of mode shape derivatives to localize damage in laminated composite plates (2014, background): “In order to minimize this problem, one needs to select an optimal spatial sampling, since mode shapes undersampling and oversampling can have adverse effects on the quality of the damage localization [18].”
Finite Element Model Updating Using Frequency Response Function of Incomplete Strain Data (2010, background): “Sazonov and Klinkhachorn [26] discussed the application of a model-based approach to locating damage with all deflection data.”
