Damage Detectability Model of Pitch-Catch Configuration in Composite Plates

open access: yesKey Engineering Materials, 2017
Detectability of damage using Lamb waves depends on many factors such as size and severity of damage, attenuation of the wave and distance to the transducers. This paper presents a detectability model for pitch-catch sensors configuration for structural health monitoring (SHM) applications.
