Riesz basis property of Timoshenko beams with boundary feedback control
A Timoshenko beam equation with boundary feedback control is considered. By an abstract result on the Riesz basis generation for the discrete operators in the Hilbert spaces, we show that the closed-loop system is a Riesz system, that is, the sequence of

Pressure–impulse diagrams of RC beams considering fire–blast interaction
Abstract When analyzing military, defense, or structures/infrastructures deemed critical, explosion‐induced actions—often associated with malicious actions—play a significant role. The combined effect of a blast and fire is not uncommon: in fact, an explosion can be the extreme consequence of a fire or vice versa, a fire can occur as the result of an ...

In this study, we address a Cauchy problem within the context of the one-dimensional Timoshenko system, incorporating a distributed delay term. The heat conduction aspect is described by the Lord-Shulman theory.

Vibrations of a Timoshenko beam on an inertial foundation under a moving load
In the paper vibrations of the Timoshenko beam on an inertial foundation subjected to a moving force are discussed. Considered model of the inertial foundation is described by three parameters.

On the stability of Timoshenko systems with Gurtin-Pipkin thermal law [PDF]
We analyze a differential system describing a Timoshenko beam coupled with a temperature evolution of Gurtin-Pipkin type. A necessary and sufficient condition for exponential stability is established in terms of the structural parameters of the equations.

In this article, the effect of Coleman-Gurtin’s and Gurtin-Pipkin’s thermal laws on the displacement of a Timoshenko beam system with suspenders is studied.

Exponential stability of Timoshenko-Gurtin-Pipkin systems with full thermal coupling [PDF]
We analyze the stability properties of a linear thermoelastic Timoshenko-Gurtin-Pipkin system with thermal coupling acting on both the shear force and the bending moment. Under either the mixed Dirichlet-Neumann or else the full Dirichlet boundary conditions, we show that the associated solution semigroup in the history space framework of Dafermos is ...

The OÆSE endstation at BESSY II: operando X‐ray absorption spectroscopy for energy materials
The OÆSE endstation at EMIL at the BESSY II synchrotron facility in Berlin allows real‐time investigation of energy materials through operando X‐ray absorption spectroscopy. The possibility to use soft, tender, and hard X‐rays combined with versatile operando sample environments enables the study of a wide range of energy materials under relevant ...

Uniform controllability for Kirchhoff and Mindlin-Timoshenko elastic systems
The Mindlin-Timoshenko operator is a perturbation of the Kirchhoff operator and it is well known that there exist solutions to the exact controllability problem for their associated systems.

Critical velocities are investigated for an infinite Timoshenko beam resting on a Winkler-type elastic foundation subjected to a harmonic moving load. The determination of critical velocities ultimately comes down to discrimination of the existence of ...
