The design of micromechanical devices that can facilitate large but recoverable deformations requires a mechanical behavior embosoms hyperelasticity. While multiphoton lithography is the epitome microscale fabrication, employed materials demonstrate linear elastic response accompanied by limited ductility. In this study, we investigate how hindrance be circumvented through pantographic structur...

This paper presents an architectured material featuring significant strain-gradient effects and called pantographic material. It is easy to fabricate, being a plate made of single continuous linear elastic containing voids. The pattern consists triangles connected by thin junctions arranged in such way that two floppy strain modes are present. A homogenization scheme based on the two-scale asym...

Pantographs are a special class of metamaterials that do not obey theories first gradient continua. In the present work, pantographic metamaterial was 3D printed and subjected to in situ torsion. The experiment designed order investigate damage onset modalities large torsional deformations mesostructures. To account for presence true pivots, multiple point constraints were implemented DVC proce...

This contribution presents the results of a campaign numerical simulations aimed at better understanding propagation longitudinal waves in pantographic beams within large-deformation regime. Initially, we recall key features Lagrangian discrete spring model, which was introduced previous works and that tested extensively as capable accurately forecasting mechanical response structures based on ...

In order to synthesize exotic metamaterials, it was proposed use as elementary components of metamaterial microstructures so-called pantographic cells. The a mesomodel based on Euler–Bernoulli nonlinear beam theory is utilized for describing their behavior when characteristic sizes are the millimeters. With an in-house code, in which connecting hinges were modeled elastic extensional and torsio...
