Mean-field limits for entropic multi-population dynamical systems
Stefano Almi, Claudio D'Eramo, Marco Morandotti +1
The well-posedness of a multi-population dynamical system with an entropy regularization and its convergence to a suitable mean-field approximation are proved, under a general set…
Non-interpenetration conditions in the passage from nonlinear to linearized Griffith fracture
Stefano Almi, Elisa Davoli, Manuel Friedrich
We characterize the passage from nonlinear to linearized Griffith-fracture theories under non-interpenetration constraints. In particular, sequences of deformations satisfying a Ci…
Mean-field selective optimal control via transient leadership
Giacomo Albi, Stefano Almi, Marco Morandotti +1
A mean-field selective optimal control problem of multipopulation dynamics via transient leadership is considered. The agents in the system are described by their spatial position…
Topology optimization for quasistatic elastoplasticity
Stefano Almi, Ulisse Stefanelli
Topology optimization is concerned with the identification of optimal shapes of deformable bodies with respect to given target functionals. The focus of this paper is on a topology…
Brittle fracture in linearly elastic plates
Stefano Almi, Emanuele Tasso
In this work we derive by Gamma-convergence techniques a model for brittle fracture linearly elastic plates. Precisely, we start from a brittle linearly elastic thin film with posi…
A Dimension-Reduction Model for Brittle Fractures on Thin Shells with Mesh Adaptivity
Stefano Almi, Sandro Belz, Stefano Micheletti +1
In this paper we derive a new two-dimensional brittle fracture model for thin shells via dimension reduction, where the admissible displacements are only normal to the shell surfac…
