Statistically equivalent surrogate material models and the impact of random imperfections on elasto-plastic response
Ustim Khristenko, Andrei Constantinescu, Patrick Le Tallec +1
Manufactured materials usually contain random imperfections due to the fabrication process, e.g., the 3D-printing, casting, etc. These imperfections affect significantly the effect…
Shape-shifting panel from 3d-printed undulated ribbon lattice
Filippo Agnelli, Michele Tricarico, Andrei Constantinescu
Materials that change their shape in response to external stimuli opens up new prospects for efficient and versatile design and shaping of three-dimensional objects. Here, we prese…
Systematic two-scale image analysis of extreme deformations in soft architectured sheets
Filippo Agnelli, Pierre Margerit, Paolo Celli +2
The multi-scale nature of architectured materials raises the need for advanced experimental methods suitable for the identification of their effective properties, especially when t…
A statistical framework for generating microstructures of two-phase random materials: application to fatigue analysis
Ustim Khristenko, Andrei Constantinescu, Patrick Le Tallec +2
Random microstructures of heterogeneous materials play a crucial role in the material macroscopic behavior and in predictions of its effective properties. A common approach to mode…
Design and testing of 3D-printed micro-architectured polymer materials exhibiting a negative Poisson's ratio
Filippo Agnelli, Andrei Constantinescu, Grigor Nika
This work proposes the complete design cycle for several auxetic materials where the cycle consists of three steps (i) the design of the micro-architecture, (ii) the manufacturing…
Design of multi-layer materials using inverse homogenization and a level set method
Grigor Nika, Andrei Constantinescu
This work is concerned with the micro-architecture of multi-layer material that globally exhibits desired mechanical properties, for instance a negative apparent Poisson ratio. We…
