Abstract: Although back-stress contributes to the mechanical properties of materials, the degree of strength enhancement from back-stress is not easy to estimate. In this research, back-stress hardening of twinning-induced plasticity (TWIP) + interstitial free (IF)-layered steel sheets were… read more here.

Abstract: Abstract Experiments and theories have suggested the evolution of intragranular back stress is primarily dependent on the characteristics and development of dislocation substructure in face-centered cubic (FCC) metals and alloys. Despite this, continuum modeling of… read more here.

DOI: 10.1016/j.jmatprotec.2019.116560
Abstract: Abstract The buckling and instability of the ultra-thin sheet metal specimens subjected to compressive loading present an evident difficulty for the investigation of Bauschinger effect by using traditional tensile-compressive loading tests. In that regard, a… read more here.

Abstract: ABSTRACT Deformation behavior of a harmonic structured material (HSM), core–shell 304L stainless steel, is investigated using micro-digital image correlation (micro-DIC). High strain-partitioning between core and shell is observed. Because the grain boundaries with a grain-size… read more here.

DOI: 10.1122/8.0000607
Abstract: We follow the assumption that the dilatational response of glassy polymers can be characterized by a back-stress type analog that includes a thermal expansion for each elastic component and with a viscosity that is dependent… read more here.
