This work deals with an experimental and numerical approach to determining the differed behavior of compressed wood elements subjected creep loading. An protocol is associated a mechanical model, whose purpose isolate effects from those shrinkage-swelling, while allowing for long duration test be conducted. The based on compression applied five wooden columns disposed in climatic room one year....

Knitted fabrics are widely used by the underwear apparel industry due to their good elasticity. Modeling the mechanical behavior of knitted fabrics using Kelvin model is one of the discussed subjects in the textile industry. The purpose of this study is to investigate the accuracy of a nonlinear Kelvin model for determining the drying behavior of knitted fabrics. To fulfill this aim, genetic al...

Abstract This study presents a thorough theoretical and experimental investigation on the nonlinear damping of in-plane micromachined electromechanical resonators. More specifically, experiments are conducted an electrically actuated bridge resonator, primary resonance response system is obtained at various AC DC voltages. A model developed using Euler–Bernoulli beam theory while accounting for...

This paper presents a numerical methodology to analyze frame structures supported on footing foundations subjected slow strains caused by consolidation settlements. A building project subsurface layer of soft soil has been analyzed. The Boundary Element Method with the Mindlin fundamental solution applied compute displacement resulting from interference between pressure bulbs foundation. rheolo...

We study the robust output regulation of linear boundary control systems by constructing extended systems. The are established based on solving static differential equations under two new conditions. We first consider abstract setting and present finite-dimensional reduced order controllers. controller design is then used for particular PDE models: high-dimensional ...

<p style='text-indent:20px;'>The three-dimensional viscoelastic fluid flow equations, arising from the motion of Kelvin-Voigt (Kelvin-Voight) fluids in bounded domains is considered this work. We investigate long-term dynamics such equations with "fading memory" (non-autonomous). first establish existence an absorbing ball appropriate spaces for semigroup defined order one (transformed au...
