Study on Stability of Elastic Compression Bending Bar in Viscoelastic Medium

open access: yesApplied Sciences, 2023
In the southeastern coastal regions of China, thick layers of marine soft soil are widely distributed, exhibiting characteristics such as high compressibility, high porosity, low strength, high sensitivity, and easy thixotropy, and these viscoelastic ...

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 ...

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.

Loss Factors of Viscoelastic Systems in Terms of Energy Concepts [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1962
The definition of loss factor in terms of energy quantities is re-examined, particularly as it applies to composite viscoelastic systems. A restatement of this definition in terms of a corresponding viscoelastic spring is used to show that this definition is extremely useful for massless (ideal viscoelastic spring) systems, but may be applied ...

Identification of Heredity Kernels and Their Influence on the Life Time of Glass/Polyester Composites

open access: yesInternational Journal of Applied Mechanics and Engineering, 2014
One of the major problems encountered in prediction of hereditary viscoelastic behavior of polymeric composites is the determination of heredity kernels.

Viscoelastic properties of multi-walled carbon nanotube/epoxy composites using two different curing cycles [PDF]

open access: yes, 2010
Along with carbon nanotubes (CNT) morphology, impurity, and functionalization, polymer curing cycle is another important factor in determining the mechanical properties of the CNT/polymer composite samples.

Polymer mechanics as a model for short-term and flow-independent cartilage viscoelasticity [PDF]

open access: yesMaterials Science and Engineering: C, 2011
Articular cartilage is the load bearing soft tissue that covers the contacting surfaces of long bones in articulating joints. Healthy cartilage allows for smooth joint motion, while damaged cartilage prohibits normal function in debilitating joint diseases such as osteoarthritis.

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 ...

Asymptotic behaviour of nonlinear viscoelastic wave equations with boundary feedback

open access: yesApplied Mathematics in Science and Engineering
In this study, we investigate a nonlinear viscoelastic wave equation subject to acoustic boundary conditions and a nonlinear distributed delay feedback acting on the boundary.
