Analytical Study on Time-Dependent Stiffness of Stud Shear Connectors

open access: yesFrontiers in Mechanical Engineering, 2022
Concrete creep weakens the spring stiffness of stud shear connectors (SSCs) and increases the long-term deflection of long-span composite beams. The time-dependent properties of SSC are of great importance for the long-term evaluation of composite steel ...

ASYMPTOTIC BEHAVIOR FOR A VISCOELASTIC WAVE EQUATION WITH A DELAY TERM [PDF]

open access: bronzeTaiwanese Journal of Mathematics, 2013
The following viscoelastic wave equation with a delay term in internal feedback: \vspace{-0.1cm} \begin{equation*} \left\vert u_{t}\right\vert ^{\rho }u_{tt}-\Delta u-\Delta u_{tt}+\int_{0}^{t}g(t-s)\Delta u(s)ds+\mu _{1}u_{t}(x,t)+\mu _{2}u_{t}(x,t-\tau )=0, \vspace{-0.1cm} \end{equation*}% is considered in a bounded domain.

Stress concentration in nonlinear viscoelastic composites

open access: yesMechanics and Advanced Technologies, 2017
A nonlinear viscoelastic problem of the mechanics of composites is solved within the framework of a second-order nonlinear theory. A viscoelastic functional is used to construct general defining relations.

Thermoplastics under Long‐Term Loading: Experiments and Viscoelastic‐Viscoplastic Modeling [PDF]

open access: yesPAMM, 2015
AbstractThe behavior of polyoxymethylene, a semicrystalline thermoplastic, with respect to mechanical long‐term loads is studied. Experiments demonstrate the creep behavior for constant load and also for cyclic unloading. The latter shows partial time‐dependent strain recovery during unloading and an extended lifetime. Based on the experimental results,

Pull-In and Snap-Through Analysis of Electrically Actuated Viscoelastic Curved Microbeam

open access: yesAdvances in Materials Science and Engineering, 2020
Microbeams are key elements in most of the micro-electromechanical systems (MEMS). Electromechanical instability of microbeams in turn plays an important role in their applications.

Exponential Growth of Solutions for Nonlinear Coupled Viscoelastic Wave Equations

open access: yesUniversal Journal of Mathematics and Applications, 2019
In this work, we consider an initial-boundary value problem related to the nonlinear coupled viscoelastic equations \[ \left\{ \begin{array}{c} \left\vert u_{t}\right\vert ^{j}u_{tt}-\Delta u_{tt}-div\left( \left\vert \nabla u\right\vert ^{\alpha -2 ...
