Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Numerical simulation of oscillations of a nonlinear mechanical system with a spring-loaded viscous friction damper [PDF]
MATEC Web of Conferences, 2019 The dynamics of a mechanical system consisting of a parallel-connected main elastic element, an external disturbance compensator having a nonlinear force characteristic, and a viscous friction damper sprung by a linear spring are studied.

Modelling and design of a dual channel magnetorheological damper [PDF]
, 2013 © Cranfield UniversityA limitation with the current analytical models for predicting the performance of a magnetorheological (MR) damper is that they fail to capture the hysteretic variation of force versus velocity variation correctly.

Advanced Engineering Materials, EarlyView.Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Optimization of nonlinear viscous damper characteristics to reduce the response of concrete structures with linear and nonlinear behaviours [PDF]
Journal of Structural and Construction Engineering, 2020 Nowadays, controlling vibration of a structure in earthquakes and reducing the structural responses are of great importance. Dampers are a type of systems controlling the absorption of the earthquake energy and dissipating it in order to reduce the ...
