Inverse Design of Metainterfaces for Static Friction Control: Beyond the Hertzian Limit
Jacopo Bilotto, Arnav Singhal, Joaquin Garcia-Suarez +3
Programming the static friction of mechanical interfaces is critical for soft robotics, haptics, and precision gripping. Static friction is governed by the real contact area, and s…
A matter of shape: contact area optimization in soft lubrication
Joaquin Garcia-Suarez
We study the fluid-mediated approach of a deformable axisymmetric object towards a rigid substrate, focusing on how its shape influences contact formation. For low approach velocit…
Data-Driven Dynamic Friction Models based on Recurrent Neural Networks
Gaëtan Cortes, Joaquin Garcia-Suarez
In this concise contribution, it is demonstrated that Recurrent Neural Networks (RNNs) based on Gated Recurrent Unit (GRU) architecture, possess the capability to learn the complex…
Fluid-mediated impact of soft solids
Jacopo Bilotto, John Martin Kolinski, Brice Lecampion +3
A viscous, lubrication-like response can be triggered in a thin film of fluid squeezed between a rigid and flat surface and the tip of an incoming projectile. We develop a comprehe…
On the lowest-frequency bandgap of 1D phononic crystals
Javier González-Carbajal, Marius Lemm, Joaquin Garcia-Suarez
This manuscript puts forward and verifies an analytical approach to design phononic crystals that feature a bandgap at the lowest possible frequencies. This new approach is verifie…
Phase-space iterative solvers
Gaëtan Cortes, Nur Cristian Sangiorgio, Joaquin Garcia-Suarez
We introduce an iterative method to solve problems in small-strain non-linear elasticity, termed ``Phase-Space Iterations'' (PSIs). The method is inspired by recent work in data-dr…
