Séminaire I2M : Fabrizio SCARPA (University of Bristol) (02 mars 2022)

with fractal slits and perforations, showing how their homogenised mechanical properties, fracture, wave propagation characteristics and linear/nonlinear damping scale with fractal orders. Gradient perforate ... Fractality, Kirigami and gradient patterns: architectures for bioinspired mechanical metamaterials

Séminaire I2M : Mme Olga BARRERA (seniot lecturer at Oxford Brookes University). (21 mai 2022)

tissues are highly porous (>60%) and functionally graded materials, mapping in space the variation of architectural features / mechanical properties is the key to the design of biomimetic synthetic tissues

Functional Materials for Acoustics (22 février 2021)

or with gradients of properties). These materials can enable tunable wavefront control or exhibit extraordinary scattering and absorption properties. We achieve high-fidelity propagation control with practical

Soutenance de thèse de Vincent Longchamp (11 mars 2024)

spraying technique is used to produce ceramic coatings with pores and cracks. This porosity has an effect on the mechanical properties of the ceramics: it attenuates the compression waves generated

Analysis and modelling of 3D variable stiffness composites produced by additive manufacturing, taking account the specific features of the process (01 septembre 2023)

on the distribution of material properties that derive from it, in order to reduce the gap between the mechanical response of the numerical model and that of the real structure. Following the work carried out at I2M

Soutenance de thèse de Michele Iacopo IZZI (04 mai 2021)

of the aeronautical field, and variable-stiffness composite structural components, characterised by a point wise variation of the macroscopic mechanical properties over the laminate surface. Concerning the formers

Sujet : Mechanical behavior and durability of earth concrete: an experimental and numerical study

politopix (23 août 2023)

the cumulative stack-up of geometric variations inside any mechanical system we need to compute Minkowski sums and intersections of sets of contraints modelled by polytopes in R6. As a consequence, we developped
