DOI: 10.1021/acs.nanolett.7b02950
Abstract: The suggestion, based on atomistic simulation, of a surface-induced tension-compression asymmetry of the strength and flow stress of small metal bodies so far lacks experimental confirmation. Here, we present the missing experimental evidence. We study… read more here.

DOI: 10.1080/21663831.2018.1478898
Abstract: ABSTRACT The residual stress significantly influences the cyclic stress response of the hierarchical nanostructured materials. An obvious tension-compression asymmetry with minimum stress in compression larger than maximum stress in tension was observed in gradient nanograined… read more here.
