Convergence of two-scale expansions for elastic heterogeneous plates Open
The aim of this article is to prove strong convergence results on the difference between the solution to highly oscillatory problems posed in thin domains and its two-scale expansion. We first consider the case of the linear diffusion equa…
MatAIRials: Inflatable Metamaterials for Freefrom Surface Design Open
Inflatable pads are used in multiple applications, e.g. as mattresses or protective equipment. In this work, we propose to treat these inflatables, made of two planar membranes sealed according to periodic patterns, typically parallel line…

Sensitivity of the Second Order Homogenized Elasticity Tensor to Topological Microstructural Changes Open
The multiscale elasticity model of solids with singular geometrical perturbations of microstructure is considered for the purposes, e.g., of optimum design. The homogenized linear elasticity tensors of first and second orders are considere…
Design Strategies for Gridshells with Singularities Open
This article discusses design strategies to improve the mechanical behavior of elastic gridshells with singularities. The advantage of meshing with one or more singularity is to allow a wider range of surfaces to be meshed with equal-lengt…

The Asymptotic Expansion Load Decomposition elastoplastic beam model Open
Summary A new higher‐order elastoplastic beam model is derived and implemented in this paper. The reduced kinematic approximation is based on a higher‐order elastic beam model using the asymptotic expansion method. This model introduces ne…
Higher‐order beam model with eigenstrains: theory and illustrations Open
A higher‐order beam model based on the asymptotic expansion method was suggested by Ferradi et al. Introducing new degrees of freedom specific to the applied loads into the kinematics of the beam, this model yields fast and accurate result…
Flexibility of nanolayers and stacks: implications in the nanostructuration of clays Open
According to the flexibility of clays stacks and their hydration state, bending or shear regimes arise at the clay layer scale.
