DOI: 10.1016/j.matlet.2021.129625
Abstract: Abstract This study represents the quantitative kink-band strengthening effect using uniaxial hot-compressed Mg-9%Y-6%Zn alloy. When room-temperature micro-Vickers indentation was performed on a specific area containing kink boundaries under a low indentation load of 10 gf, the… read more here.

DOI: 10.1177/00219983221114012
Abstract: A multiscale model for compression kink band failure in fibrous composites is presented. The computational model predicts the progression of damage associated with the formation of kink bands, which experiments demonstrate to involve excessive shear… read more here.
