Abstract: An improved formula considering the change in densification strain is derived to predict the quasi-static crushing stress of gradient foam material. Besides, a two-displacement field is proposed to describe the deformation of negative gradient foam… read more here.

DOI: 10.1557/jmr.2018.72
Abstract: We present classical potential molecular dynamics simulations of nanoporous gold (np-Au) impacted by a spherical indenter. The atomic structure was generated using a phase field model as a template. In agreement with previous experiments, we… read more here.
