Auxetic mechanical metamaterials are artificially architected materials that possess negative
Poisson's ratio, demonstrating transversal contracting deformation under external vertical …

Auxetic behavior is a promising new area for use in defense applications. In comparison to a
conventional material, an auxetic material has superior properties because of having a …

In this work, an experiment according to the full factorial method (FFM) to investigate the
effect of initial helical angle of wrap component, diameter ratio of components and modulus …

Natural fibers are gaining importance due to environmental concerns and sustainability
issues. However, their mechanical performance is not up to the mark. To overcome this …

Multi-ply yarns have been used as the main structure to form strands, braids, and fabrics.
Thus, various strategies including experimental, numerical, and analytical models have …

In this paper, the tensile models of the negative Poisson's ratio yarn with incompressible
component yarn and compressible component yarn are constructed. The theoretical …
