Property optimization of porous metallic glasses via structural design

Systematization of material parameters is essential for property optimization. In this work, a gradient-extended continuum mechanical model implemented into a finite element code is utilized to analyze the influence of pore hierarchy on the overall mechanical response of porous metallic glasses. A spectrum of samples with randomized (stochastic) pore designs is comparatively studied with their periodic counterparts. It is shown that the pore design as well as the volume fraction has a strong effect on the mechanical response of the porous metallic glass structures. The results underline design aspects for certain applications. © 2014 The Authors
