Negative Pressure Waves Analysis for Crack Localization and Crack Size Estimation for 3D Printed SHM system

Onderzoeksoutput: Conference paper

Samenvatting

A new Structural Health Monitoring system was developed to allow
a faster introduction of 3D printed components into safety critical appli-
cations. Additive manufacturing techniques are used to embed capillaries
in the 3D printed structure that are then pressurized. Continuous moni-
toring of the capillary pressure allows the system to indicate the existence
of a crack when the pressure deviates from the initial pressure level. A
specically developed experimental set-up enables the study of the impact
of dierent parameters on the leak flow behaviour and the occurring Nega-
tive Pressure Waves. Negative Pressure Waves are analysed to demonstrate
the crack localization and crack size estimation feasibility. It will rst be
theoretically proven that the size and location of the crack can be derived
from the Negative Pressure Waves. Secondly, measurements will validate
the crack localization and size estimation feasibility of the new Structural
Health Monitoring system.
