Article Snippet: From observations of the longitudinal cross-section of the crushed absorbers , it was found that folds of the Docol 1200M tube absorber have a lower depth in comparison to Docol 1000DP ( m > n ), which means that the stiffness and springback of the Docol 1200M tube absorber are higher than the Docol 1000DP one.
