What is it about?
The use of auxetic materials is useful for reducing the maximum bending stresses for elliptical plates of aspect ratio close to 1, while conventional materials are more advantageous for elliptical plates of higher aspect ratio.

Why is it important?
This study is important as it proposes an additional avenue for reducing bending stresses in elliptical plates.
Perspectives
Although the title of this paper mentions auxetic plates, the analysis and plotted results cover the entire range of Poisson's ratio within the context of isotropic solids. As such the developed model is applicable for elliptical plates of positive and negative Poisson's ratio.
