Dynamic Response Assessment of Impact Meta-Dampers
(2022)Recently, the concept of metamaterials, initially studied for electromagnetic applications has gained interest within a civil engineering context. It has been shown that periodic arrangement of resonators, referred to as unit cells, can provide beneficial properties in vibration absorption, within a specific range of frequencies, the so-called bandgap. In order to take advantage of the full potential these unique structures can offer, a ...Other Conference Item -

Earthquake-Induced Damage Estimation in Structural Systems using Parametric Physics-Based Reduced-Order Models
(2021)Structural systems are usually characterized by complex dynamic response under earthquake or damage events, which extends beyond the expected behavior during regular operational conditions, posing thus unique and challenging requirements for designing and utilizing digital twins. Such representations have become indispensable due to the ongoing virtualization, and their efficiency in addressing such phenomena is critical, especially in ...Other Conference Item -
Reduced Order Modeling for systems with component nonlinearities
(2021)Deriving digital twins of real-life dynamical systems is an intricate modeling task. These representations have gained significance in the current virtualization era, thus bringing Reduced Order Models (ROMs) in the foreground. An efficient low-order representation should capture nonlinear effects, while retaining any dependencies of the real-life system over system- and loading-related traits. Several schemes have been proposed in this ...Other Conference Item -

A Deflated Conjugate Gradient Solver for Extended Finite Element Models
(2021)In finite element analysis for solid mechanics, the solution of the linear system of equations represents the performance bottleneck in terms of both computation time and memory storage. For this task, direct solvers are a common choice due to their simplicity and robustness, however the very large amount of memory required to factorize the stiffness matrix precludes the solution of medium to large-sized problems. For this reason, ...Other Conference Item -
