Abstract
Experimental confirmation is provided for a brittle‐to‐ductile transition of the spall failure mode in a 6061‐T6 aluminum alloy, at a strain rate of 107 s−1 , caused by laser‐induced shock waves. This result is consistent with the prediction of a theory that has been put forward recently by Grady. The experimental approach that was used allowed determination of the maximum elongation associated with the spall failure in the alloy and pure aluminum.Keywords
