“…In the present study, hollow ligaments are thought as cylindrical solid ones with equivalent radius r, since that the cylindrical specimens were confirmed to give more accurate results on electrical properties [13]. The equivalent diameter in a tetrakaidecahedral (K) unit cell is then expressed as [26]:…”

“…At a thickness of 0.45 mm, the single-layer material has a shielding efficiency of S E = 10–12 dB. X. Huang et al [ 10 ] prepared Fe–Ni foam materials for shielding in the lower frequency range and explored their shielding performance. The composite perforated foam material has excellent magnetic shielding performance in the frequency range of 10–500 kHz, and the single-layer material with a thickness of 0.25–0.36 mm has a shielding efficiency of S E = 20–60 dB.…”

Considering the magnetic shielding requirements of both geomagnetic field and 50 Hz power-line frequency in the complex working conditions of the power grid, an electromagnetic shielding system combining active and passive modes is proposed in this article. A three-dimensional Helmholtz coil with a magnetic shielding barrel nested inside is established by the COMSOL simulation tool, and the magnetic shielding efficiency of the system is analyzed. Comparing different materials, the simulation results indicate that permalloy alloy exhibits better shielding performance than pure iron and nickel materials. Additionally, the overall shielding efficiency of the shielding barrel increases linearly with the number of multiple layers. Under the combined active and passive electromagnetic shielding conditions, the system achieves a shielding efficiency of SE = 113.98 dB, demonstrating excellent performance in shielding both AC and DC interference magnetic fields. This study provides theoretical guidance for the construction of magnetic shielding systems in electromagnetic interference environment.

“…Porous materials can be widely applied in a number of engineering fields, involving separation, filtration, heat exchange, biological transplanting, electrochemical process and lightweight structures (Liu and Ma, 2020; Yusuf and Jha, 2018; Liu and Chen, 2014; Atwater et al , 2018), with the reticular metal foam (Plate 1) as a quite representative example (Liu and Ma, 2020; Atwater et al , 2018; August et al , 2016; Chen et al , 2018). In order to use these materials more effectively and reasonably, the research on their mechanical properties has aroused extensive interests (Gibson and Ashby, 1999; Xiao et al , 2015; Jung and Diebels, 2017; Huang et al , 2008, 2012; Benedik et al , 2010; Aly, 2010a, b; Soni and Biswas, 2018; Zhou et al , 2014; Tang et al , 2014; Palka et al , 2016; Wu et al , 2019; Schueler et al , 2013; Pang et al , 2011; Cho et al , 2019; Kaya and Fleck, 2014; Yang et al , 2019; Shi et al , 2017), and the present authors have also done some relevant works (Liu and Ma, 2020; Liu, 2000, 2004a, b, c, 2006, 2007, 2010a, b, c, 2011; Liu et al , 2003, 1999a, 2001a, b, 2009, 2011; Liu and Chen, 2009; Liu and Du, 2011, 2012). The published researches on the failure mode are mainly focused on metal foams under uniaxial tension and compression, while quite rare on that under other loading forms.…”

PurposeThe purpose of this paper is to provide a summarization and review of the present author's main investigations on failure modes of reticular metal foams under different loadings in engineering applications.Design/methodology/approachWith the octahedral structure model proposed by the present authors themselves, the fundamentally mechanical relations have been systematically studied for reticular metal foams with open cells in their previous works. On this basis, such model theory is continually used to investigate the failure mode of this kind of porous materials under compression, bending, torsion and shearing, which are common loading forms in engineering applications.FindingsThe pore-strut of metal foams under different compressive loadings will fail in the tensile breaking mode when it is brittle. While it is ductile, it will tend to the shearing failure mode when the shearing strength is half or nearly half of the tensile strength for the corresponding dense material and to the tensile breaking mode when the shearing strength is higher than half of the tensile strength to a certain value. The failure modes of such porous materials under bending, torsional and shearing loads are also similarly related to their material species.Originality/valueThis paper presents a distinctive method to conveniently analyze and estimate the failure mode of metal foams under different loadings in engineering applications.
