An experimental damage tolerance investigation of CFRP composites on a substructural level
Composites Part C: Open Access, 2022 The damage tolerance (DT) allowables for the design of a composite structure are typically determined through experiments on the coupon level. The present study examines the transferability of the DT behavior from the coupon level to a structural level ...

Equivalence of disturbance observer structures for linear systems [PDF]
, 2000 Several techniques exist to incorporate disturbance rejection requirements in a linear controller design. Contrary to, for example the H-infinity controller design technique where only one degree of freedom is available to obtain both disturbance ...

Integrated Shock Absorber With Both Tunable Inertance and Damping
Frontiers in Materials, 2020 Inerter is a two-terminal mass element, and the applied force is proportional to the relative acceleration between the terminals. According to the second class of mechanical–electrical analogy, the inerter corresponds exactly to the capacitor in the ...

Dissipative structures in biological systems: bistability, oscillations, spatial patterns and waves
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 The goal of this review article is to assess how relevant is the concept of dissipative structure for understanding the dynamical bases of non-equilibrium self-organization in biological systems, and to see where it has been applied in the five decades ...
