Damage Evolution Analysis in a “Spaghetti” Bridge Model Using the Acoustic Emission Technique

Damage Evolution Analysis in a “Spaghetti” Bridge Model Using the Acoustic Emission Technique

This paper applies the Acoustic Emission (AE) Technique to analyze the damage process in a one-meter span bridge model that was built from spaghetti sticks during a loading test. The AE signals are analyzed in terms of four coefficients that are evaluated as predictors of structure failure, with fre...
