Wave propagation through alumina-porous alumina laminates
Pathikumar Sellappan, Erheng Wang, Christian J. Espinoza Santos +3
A Brazilian disk geometry of an alumina layered composite with alternating dense and porous layers was dynamically loaded using a Split-Hopkinson Pressure Bar (SHPB)apparatus under…
Predicting Failure: Acoustic Emission of Berlinite under Compression
Guillaume F Nataf, Pedro O Castillo-Villa, Pathikumar Sellappan +4
Acoustic emission has been measured and statistical characteristics have been analyzed during the stress-induced collapse of porous berlinite, AlPO4, containing up to 50 vol% poros…
Crackling noise during failure of alumina under compression: effect of porosity
Pedro O Castillo-Villa, Jordi Baró, Antoni Planes +4
We study the acoustic emission avalanches during the failure process of porous alumina samples (Al2O3) under compression. Specimens with different porosities ranging from 30% to 59…
