Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A special kind of pentamode metamaterial, which is composed of double-cone elements and forms simple-cubic lattice, is investigated in this paper. Based on finite-element method, the phonon band structure and the transmission spectrum of the pentamode metamaterial are calculated, and then the pentamodal behavior of this structure is theoretically verified from two aspects, i.e. the physical properties and the mathematical definition. Results show that in the phonon band structure, there is a wider single-mode band gap, corresponding to the remarkable loss in the transmission spectrum. The ratio of bulk modulus B to shear modulus G is more than 300, which is obviously larger than that of traditional materials. Except for the isotropic bulk modulus B, the other mechanical moduli are all anisotropic. Five of six eigenvalues of elastic coefficient matrix are nearly zero for the microstructure, and only one is non-zero. These results demonstrate that this metamaterial microstructure performs excellent pentamodal characteristics, and also conforms to the mathematical definition of 'pentamode'.
