Competitive Bidirectional Response in Bi‐Polymeric Mechanochromic Cantilevers Toward Color Imaging‐Based VOC Discrimination

open access: yesAdvanced Optical Materials, Volume 13, Issue 32, November 14, 2025.
In bi‐polymeric mechanochromic cantilevers composed of polydimethylsiloxane (PDMS) and off‐stoichiometry thiol‐ene‐epoxy (OSTE+), differential swelling between the two polymers in response to VOC exposure induces a competitive bidirectional bending and corresponding color changes, with three characteristic response modes related to the Hansen ...

On the Equivalence between Static and Dynamic Railway Track Response and on the Euler-Bernoulli and Timoshenko Beams Analogy

open access: yesShock and Vibration, 2017
The paper tries to clarify the problem of solution and interpretation of railway track dynamics equations for linear models. Set of theorems is introduced in the paper describing two types of equivalence: between static and dynamic track response under ...

On Stability of Hyperbolic Thermoelastic Reissner-Mindlin-Timoshenko Plates

open access: yes, 2013
In the present article, we consider a thermoelastic plate of Reissner-Mindlin-Timoshenko type with the hyperbolic heat conduction arising from Cattaneo's law. In the absense of any additional mechanical dissipations, the system is often not even strongly

Encapsulation Strategies for OLEDs: From Conventional Devices to Flexible and Biointegrated Applications

open access: yesAdvanced Electronic Materials, Volume 11, Issue 19, November 18, 2025.
Organic light‐emitting diodes (OLEDs) face degradation from moisture, oxygen, heat, and mechanical stress, especially in wearable and bioelectronic devices. This review highlights conventional and advanced encapsulation approaches, barrier evaluation techniques, and degradation mechanisms.

Sensing linear viscoelastic constitutive parameters with a Timoshenko beam on a multi-layer foundation: Modeling and simulation

open access: yesSensing and Bio-Sensing Research, 2015
We present a sensor model comprised of a Timoshenko beam coupled with a linear viscoelastic substrate via a distributed system of compliant elements. The system of governing equations includes the evolution of the kinematic descriptors of the Timoshenko ...

Shape optimization of a Timoshenko beam together with an elastic foundation [PDF]

open access: yes, 2010
In this article we are going first to aim at the variational ormulation of the bending problem for the Timoshenko beam model. Afterwards we will extend this problem to the Timoshenko beam resting on the Winkler foundation, which is firmly connected with

Exponential stability for infinite-dimensional non-autonomous port-Hamiltonian Systems

open access: yes, 2019
We study the non-autonomous version of an infinite-dimensional port-Hamiltonian system on an interval $[a, b]$. Employing abstract results on evolution families, we show $C^1$-well-posedness of the corresponding Cauchy problem, and thereby existence and ...

On the Stabilizability of a Slowly Rotating Timoshenko Beam

open access: yesZeitschrift für Analysis und ihre Anwendungen, 2000
In this paper we continue our investigation of a slowly rotating Timoshenko beam in a horizontal plane whose movement is controlled by the angular acceleration of the disk of a driving motor into which the beam is clamped. We show how to choose a feedback control allowing to stabilize our system (the beam plus the disk) in a preassigned position of ...

A Family of Higher‐Order Theories for Wave Propagation in One‐Dimensional Structural Elements

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 19, 15 October 2025.
ABSTRACT This paper proposes a systematic framework for the development and classification of higher‐order theories for modeling wave propagation in one‐dimensional structural elements. Building upon and organizing the existing higher‐order models, a generalized approach is introduced to construct an entire family of such theories with controllable ...
