Abstract

The acoustic emission (AE) response during compression and indentation of different kinds of aluminum foam was recorded and evaluated with respect to the various stages of the deformation process. During compression continuous AE response was measured, while during indentation a response consisting of individual AE events was monitored. Studying these individual signals during indentation permits to study the changes in deformation mechanisms during compression.
