Poisson’s Ratios of 2D Honeycomb-Structured Polymer Sheets |
| 초록 |
The mechanical properties of 2D honeycomb-structured polymer sheets are examined with respect to the several polar angle. The tensile force fluctuates as an undamped negative sinusoidal wave with a periodicity of 15°. The amplitude of the fluctuation is proportional to the thickness of the polymer sheets, but the Young’s modulus is independent of the thickness and the polar angle. Total and local Poisson’s ratios of polymer sheets at the 30° polar angle are lower than those obtained at the 0° polar angle over the entire strain range, and the difference becomes smaller. The experimentally observed structure-property relationship of the polymer sheets can provide important clues for understanding the deformation behavior of patterned polymeric materials. |
