Crack Identification in Necked Double Shear Lugs by Means of the Electro-Mechanical Impedance Method

Markus Winklberger et al.

Summary: This study investigates fatigue crack detection, localization, and quantification in necked lugs using piezoelectric transducers and the electro-mechanical impedance (EMI) method. Numerical simulations and experiments validate a two-step analysis approach to reliably identify fatigue cracks at critical locations in necked lugs.

Vibration-Based Thermal Health Monitoring for Face Layer Debonding Detection in Aerospace Sandwich Structures

Thomas Bergmayr et al.

Summary: This study investigates a novel vibration-based thermal health monitoring method for continuous and on-board damage detection in fiber reinforced polymer sandwich structures commonly used in aerospace applications. By using piezoelectric wafer active sensors as excitation source and surface temperature sensors instead of infrared cameras, the study overcomes key hindrances for vibration-based thermography applications in real-life structures.

On the Capability of Measuring Actual Strain Values With Electrical Impedance Tomography Using Planar Silkscreen Printed Elastoresistive Sensors

Jonas Wagner et al.

Summary: This paper introduces a method to measure strain through 2D Electrical Impedance Tomography (EIT) combined with a planar elastoresistive sensor, allowing simultaneous and spatial strain and damage monitoring by a single sensor. The importance of selecting a suitable hyperparameter for the EIT reconstruction algorithm is discussed, with a selection approach based on the combinational use of the L-Curve (LC) method and the Fixed Noise Figure (NF) method.
