Sound transmission loss enhancement through triple-peak coupled resonances acoustic metamaterials
(2024-03-15)
Article
Open AccessCoupled resonances mechanisms combined with the notion of acoustic metamaterials offer exceptional sound insulation capabilities, even at the challenging low frequency ranges below 1000 Hz. In this context, the concept of ... -
Machine learning in solid mechanics: Application to acoustic metamaterial design
(John Wiley & sons, 2024-07-30)
Article
Open AccessMachine learning (ML) and Deep learning (DL) are increasingly pivotal in the design of advanced metamaterials, seamlessly integrated with material or topology optimization. Their intrinsic capability to predict and ... -
Optimal design of Multiresonant Layered Acoustic Metamaterials (MLAM) via a homogenization approach
(Elsevier, 2023-10)
Article
Open AccessBroadband sound attenuation at low frequency ranges (below 500 Hz) has been a challenge in the acoustics field which cannot be solved, via conventional materials, unless impractical amounts of mass are employed. Multiresonant ... -
Poro-viscoelastic material parameter identification of brain tissue-mimicking hydrogels
(Frontiers Media SA, 2023-04-10)
Article
Open AccessUnderstanding and characterizing the mechanical and structural properties of brain tissue is essential for developing and calibrating reliable material models. Based on the Theory of Porous Media, a novel nonlinear ... -
The role of computational models in mechanobiology of growing bone
(Frontiers Media SA, 2022-11-18)
Article
Open AccessEndochondral ossification, the process by which long bones grow in length, is regulated by mechanical forces. Computational models, specifically finite element models, have been used for decades to understand the role of ... -
I’m stuck! How to efficiently debug computational solid mechanics models so you can enjoy the beauty of simulations
(2023-01)
Article
Open AccessA substantial fraction of the time that computational modellers dedicate to developing their models is actually spent trouble-shooting and debugging their code. However, how this process unfolds is seldom spoken about, ... -
Coiled phononic crystal with periodic rotational locking: subwavelength bragg band gaps
(American Physical Society (APS), 2022-07-15)
Article
Open AccessPhononic crystals (PnC) are spatially periodic materials with band gaps that form by Bragg scattering of elastic waves. Within the frequency range of a band gap, wave propagation is not admitted. A long-standing limitation ... -
Usability of deep learning pipelines for 3D nuclei identification with Stardist and Cellpose
(Elsevier, 2022-12)
Article
Open AccessSegmentation of 3D images to identify cells and their molecular outputs can be difficult and tedious. Machine learning algorithms provide a promising alternative to manual analysis as emerging 3D image processing technology ... -
Local mechanical stimuli correlate with tissue growth in axolotl salamander joint morphogenesis
(2022-05-25)
Article
Open AccessMovement-induced forces are critical to correct joint formation, but it is unclear how cells sense and respond to these mechanical cues. To study the role of mechanical stimuli in the shaping of the joint, we combined ... -
Design of an intake and a thruster for an atmosphere-breathing electric propulsion system
(2022-10)
Article
Open AccessChallenging space missions include those at very low altitudes, where the atmosphere is the source of aerodynamic drag on the spacecraft, that fnally defnes the mission’s lifetime, unless a way to compensate for it is ... -
Development and analysis of novel mission scenarios based on Atmosphere-Breathing Electric Propulsion (ABEP)
(2022-10)
Article
Open AccessOperating satellites in Very Low Earth Orbit (VLEO) benefit the already expanding New Space industry in applications including Earth Observation and beyond. However, long-term operations at such low altitudes require ... -
Towards shock absorbing hyperelastic metamaterial design. (I) Macroscopic scale: computational shock-capturing
(2022-04)
Article
Open AccessThe work explores the computational modeling of propagating shocks in hyperelastic materials to be considered in the context of numerical analysis and design of mechanical energy absorbing materials. The computational ...
