Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control
Advanced Engineering Materials, EarlyView.This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Stability of second-order differential inclusions
Electronic Journal of Differential Equations, 2011 For an arbitrary second-order stable matrix A, we calculate the maximum positive value R for which the differential inclusion $$ dot{x}in F_{R}(x):={(A+Delta)x, Delta in mathbb{R}^{2imes 2}, |Delta | leq R } $$ is asymptotically stable.

Stability of Liquid Bridges between Unequal Disks under Zero-Gravity Conditions [PDF]
, 1995 The stability, of axisymmetric equilibrium shapes of a liquid bridge between two coaxial disks of different radii under zero-gravity conditions is investigated. The stability regions have been evaluated for different values of the ratio of the disk radii

Wind-shearing in gaseous protoplanetary disks and the evolution of binary planetesimals
, 2011 One of the first stages of planet formation is the growth of small planetesimals. This early stage occurs much before the dispersal of most of the gas from the protoplanetary disk. Due to their different aerodynamic properties, planetesimals of different

Advanced Engineering Materials, EarlyView.This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Robust stability of patterned linear systems
Electronic Journal of Differential Equations, 2013 For a Hurwitz stable matrix $A\in \mathbb{R}^{n\times n}$, we calculate the real structured radius of stability for $A$ with a perturbation $P=B\Delta (t)C$, where $A, B, C$, $ \Delta (t)$ form a patterned quadruple of matrices; i.e., they are ...

An Inkjet‐Printed Platinum‐Based Temperature Sensing Element on Polyimide Substrates
Advanced Engineering Materials, EarlyView.An inkjet‐printed, meander‐structured, nanoparticle platinum‐based resistive temperature sensors on polyimide substrates are demonstrated as proof‐of‐concept. Optimized sintering at 250°C enables stable conductive structures. The Pt100‐ and Pt1000‐type sensors exhibit linear resistance–temperature characteristics with stable TCR in the 20°C–80°C range,
