Hencky (Über die angenäherte Lösung von Stabilitätsproblemen im Raum mittels der
elastischen Gelenkkette. Ph. D. thesis, Engelmann, 1921) proposed a discrete model for …

The well-posedness of the boundary value problems for second gradient elasticity has been
studied under the assumption of strong ellipticity of the dependence on the second …

There is a class of planar 1D-continua which can be described exclusively by their
placement functions which in turn are curves in a two-dimensional space. In contrast to the …

Since the works by Gabrio Piola, it has been debated the relevance of higher-gradient
continuum models in mechanics. Some authors even questioned the logical consistency of …

In order to design the microstructure of metamaterials showing high toughness in extension
(property to be shared with muscles), it has been recently proposed (Dell'Isola et al. in Z …

The central theme of this study is to investigate a remarkable capability of a second-gradient
continuum model developed for pantographic structures. The model is applied to a particular …

The aim of this paper is to find a computationally efficient and predictive model for the class
of systems that we call 'pantographic structures'. The interest in these materials was …

Complex problems such as those concerning the mechanics of materials can be confronted
only by considering numerical simulations. Analytical methods are useful to build guidelines …

We present a theoretical and numerical framework to compute bifurcations of equilibria and
stability of slender elastic rods. The 3D kinematics of the rod is treated in a geometrically …

A linear elastic second gradient orthotropic two-dimensional solid that is invariant under 90^
∘ 90∘ rotation and for mirror transformation is considered. Such anisotropy is the most …
