Here a cohesive finite element method is employed to investigate the paradox of a brittle nanostructured interface (nanograined interface layer) and a ductile layered stainless steel. Parametric studies show that the more brittle the nanograined interface layer is, the more micro-cracks the nanograined interface layer has, and the more ductile the layered stainless steel is.enjournal article10.1016/j.scriptamat.2010.04.035
