MS20 - Synchronization Dynamics, Collective Behaviors and Nonlinear Mechanics

The study explores impact-induced nonlinear wave phenomena in one-dimensional assemblies of bistable tensegrity prisms. Each unit cell consists of an all-bar prism characterized by a two-well axial equilibrium path—either strain-softening or strain-hardening—periodically coupled with concentrated masses. Finite-chain numerical analyses are conducted to characterize the initiation, evolution,...

MS20 - Synchronization Dynamics, Collective Behaviors and Nonlinear Mechanics

Dry friction is commonly present in mechanical structures through joints and interfaces, introducing nonlinear phenomena such as stick–slip transitions and partial locking. While friction is often regarded as a source of damping, recent studies have shown that it can significantly influence vibration-based damage detection, sometimes enhancing damage signatures and sometimes masking...

106. Coupling flutter instability and electromagnetic interactions in a “virtual” microrobotics experiment

MS20 - Synchronization Dynamics, Collective Behaviors and Nonlinear Mechanics

Bio-inspired microrobots are widely investigated as controllable devices for swimming in aqueous environments since their trajectories can be guided via the use of Lorentz-type forces [1]. Yet, the effectiveness of the electromagnetic interaction depends strongly on the locomotion mechanism [2] of the device. At low Reynolds numbers, some propulsion strategies are characterized by flutter...

143. Thermo-Mechanical Instabilities in Snow Slabs Avalanches: An Ab-Initio Quantized Fracture Thermo-Mechanics (QFTM) Approach

Claudia Binetti (University of Trento)

MS20 - Synchronization Dynamics, Collective Behaviors and Nonlinear Mechanics

Climate change is significantly affecting mountain environments, with increasing temperatures altering snowpack stability and potentially increasing the frequency of snow-slab avalanches. Understanding how temperature influences avalanche triggering is therefore crucial for assessing the impact of warming climates on snow hazards. Although field observations consistently indicate that...

161. Inelastic effective properties of bone-like tissue via Asymptotic Homogenization

Alessandro Giammarini (Politecnico di Milano)

MS20 - Synchronization Dynamics, Collective Behaviors and Nonlinear Mechanics

Cortical bone is an example of a multiscale biological tissue, being characterized by a sharp separation between the macroscopic lenght scale, at which the cortical bone appears like a continuum with defined structural biological functionality, and the microscopic length scale, at which it is possible to identify an elementary unit, i.e. the lamella, that, when repeated, composes the tissue....
