Analysis of acoustic emission activity during progressive failure in heterogeneous materials : experimental and numerical investigation
Friedrich, Leandro Ferreira; Tanzi, Boris Nahuel Rojo; Colpo, Angélica Bordin; Sobczyk Sobrinho, Mario Roland; Lacidogna, Giuseppe; Niccolini, Gianni; Iturrioz, Ignacio (2022) [Artigo de periódico]This work focuses on an experimental and numerical investigation into monitoring damage in a cube-shaped concrete specimen under compression. Experimental monitoring uses acoustic emission (AE) signals acquired by two ... -
Damage evolution analysis in a “spaghetti” bridge model using the acoustic emission technique
Tanzi, Boris Nahuel Rojo; Sobczyk Sobrinho, Mario Roland; Becker, Tiago; Segovia Gonzalez, Luis Alberto; Vantadori, Sabrina; Iturrioz, Ignacio; Lacidogna, Giuseppe (2021) [Artigo de periódico]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 ... -
Damage evolution in quasi-brittle materials : experimental analysis by AE and numerical simulation
Tanzi, Boris Nahuel Rojo; Iturrioz, Ignacio; Sobczyk Sobrinho, Mario Roland; Lacidogna, Giuseppe (2023) [Artigo de periódico]This work investigates the extension of a total-collapse prediction method to include local failures in quasi-brittle materials as they undergo damage processes. The analysis is experimentally conducted with acoustic ... -
Long-range correlations and natural time series analyses from acoustic emission signals
Friedrich, Leandro Ferreira; Cezar, Édiblu Silva; Colpo, Angélica Bordin; Tanzi, Boris Nahuel Rojo; Sobczyk Sobrinho, Mario Roland; Lacidogna, Giuseppe; Niccolini, Gianni; Kosteski, Luis Eduardo; Iturrioz, Ignacio (2022) [Artigo de periódico]This work focuses on analyzing acoustic emission (AE) signals as a means to predict failure in structures. There are two main approaches that are considered: (i) long-range correlation analysis using both the Hurst (H) and ... -
Truss-like discrete element method applied to damage process simulation in quasi-brittle materials
Tanzi, Boris Nahuel Rojo; Birck, Gabriel; Sobczyk Sobrinho, Mario Roland; Iturrioz, Ignacio; Lacidogna, Giuseppe (2023) [Artigo de periódico]This paper discusses the combined application of the lattice discrete element method (LDEM) and the acoustic emission (AE) technique to analyze damage in quasi-brittle materials. These methods were used to study the damage ...
