The modal damping ratio of a Single-Degree-of-Freedom (SDOF)
, 2023 Abstract Both NeXT and RDT techniques have their advantages and limitations, and the choice between them depends on the specific requirements and characteristics of the structural system being analyzed. It's recommended to consult relevant literature or seek guidance from experts to ensure accurate and reliable computation of the free-decay ...

Estimation of Modal Damping Ratios from Mode Indicator Function.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1997 The authors propose the utilization of a MIF (mode indicator function) to estimate modal damping ratios approximately. The accuracy and the effect of this method are examined to determine its feasibility for use in experimental modal parameter identification.

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 ...

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 ...
