Conformal-type energy estimates on hyperboloids and the wave-Klein-Gordon model of self-gravitating massive fields

open access: yesCommunications in Analysis and Mechanics, 2023
In this article we revisit the global existence result of the wave-Klein-Gordon model of the system of the self-gravitating massive field. Our new observation is that, by applying the conformal energy estimates on hyperboloids, we obtain mildly ...

Nonlinear stability of viscous roll waves [PDF]

open access: yes, 2010
Extending results of Oh--Zumbrun and Johnson--Zumbrun for parabolic conservation laws, we show that spectral stability implies nonlinear stability for spatially periodic viscous roll wave solutions of the one-dimensional St.

Thermomechanical nonlinear stability of pressure-loaded CNT-reinforced composite doubly curved panels resting on elastic foundations

open access: yesNonlinear Engineering, 2019
Nonlinear stability of nanocomposite spherical and cylindrical panels reinforced by carbon nanotubes (CNTs), resting on elastic foundations and subjected to uniform external pressure in thermal environments is investigated in this paper.

Nonlinear Dynamic Stability of Cylindrical Reticulated Shells with Initial Damage

open access: yesBuildings, 2023
As large-span structures, reticulated shells are widely used in large-scale public building and act as emergency shelters in the event of sudden disasters.

Stability of Planar Nonlinear Switched Systems [PDF]

open access: yes, 2005
We consider the time-dependent nonlinear system $\dot q(t)=u(t)X(q(t))+(1-u(t))Y(q(t))$, where $q\in\R^2$, $X$ and $Y$ are two %$C^\infty$ smooth vector fields, globally asymptotically stable at the origin and $u:[0,\infty)\to\{0,1\}$ is an arbitrary ...

Thermal stability analysis of eccentrically stiffened Sigmoid-FGM plate with metal–ceramic–metal layers based on FSDT

open access: yesCogent Engineering, 2016
This paper researches the thermal stability of eccentrically stiffened plates made of functionally graded materials (FGM) with metal–ceramic–metal layers subjected to thermal load. The equilibrium and compatibility equations for the plates are derived by

Nonlinear thermo-mechanical stability of shear deformable FGM sandwich shallow spherical shells with tangential edge constraints

open access: yesVietnam Journal of Mechanics, 2017
This paper presents an analytical approach to investigate the nonlinear axisymmetric response of moderately thick FGM sandwich shallow spherical shells resting on elastic foundations, exposed to thermal environments and subjected to uniform external ...

Stability of Compacton Solutions of Fifth-Order Nonlinear Dispersive Equations

open access: yes, 2000
We consider fifth-order nonlinear dispersive $K(m,n,p)$ type equations to study the effect of nonlinear dispersion. Using simple scaling arguments we show, how, instead of the conventional solitary waves like solitons, the interaction of the nonlinear ...

Stability of Spatial Optical Solitons [PDF]

open access: yes, 2000
We present a brief overview of the basic concepts of the soliton stability theory and discuss some characteristic examples of the instability-induced soliton dynamics, in application to spatial optical solitons described by the NLS-type nonlinear models ...
