Mathematical modelling of a rectangular sandwich plate with a metal foam core (2011, background): “Banhart (2001), Bart-Smith et al. (2001), and Hohe and Becker (2002) presented the manufacture, characterization and application of cellular metals and metal foams for sandwich structures.”
Homogenization of corrugated core sandwich panels (2003, methodology): “Therefore, as noted in [11], this method is more appropriate than the homogenization of the core into an equivalent medium separately (see [4] for cellular sandwich cores), even if the latter may incorporate core face sheet constraints [13].”
Computational homogenization for heterogeneous thin sheets (2010, methodology): “Next, the whole sandwich structure can be analyzed by application of appropriate laminate composite theory (see the review paper by Hohe and Becker [2], and references therein, and a more recent publication [3]) or by performing finite element simulations with only a few finite elements for the homo”
Characterization of Nomex honeycomb core constituent material mechanical properties (2014, methodology): “With an increased cell hexagon angle (u = 60 ), we could expect a correction in the GL/GW ratio according to analytical models [49].”
