background: laser-tissue interaction on low-level laser therapy (lllt) has widespread medical applications (e.g., improved wound healing). the tensile strength of radiated tissue by lllt is known to be increased mainly because of cross collagen bands developed after radiation. objective: in this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic t...

Viscoelasticity and roughness are among the possible causes of adhesive hysteresis displayed by soft contacts. an increased effective work adhesion due to stiffening contact, while is responsible for elastic instabilities. Herein, we explore interplay between viscoelasticity simulating in two dimensions retraction a rigid cylinder, with wavy surface profile, from viscoelastic half-space. The wa...

In the present paper, a new type of surface-bonded fiber Bragg grating (FBG) dynamometry bolt is designed. It assumed that adhesive layer linear viscoelastic material and its creep mechanical behavior expressed by standard solid model. The shear strain transfer model FBG sensor established. Additionally, instantaneous quasistatic functions are obtained. validated uniaxial tensile test long-term...

Abstract It is still little or no knowledge about the properties of layered wood-based composites and nonwood components in viscoelastic plastic region force-deflection diagram (FDD). The this area are influenced by several factors such as composition composite, method modification individual layers, type adhesive used, etc. This paper focuses on analysis effect thickness layers (5 9 mm) beech ...

Polymers are increasingly being used in higher demanding applications due to their ability tailor the properties of structures while allowing for a weight and cost reduction. Solvents play an important role manufacture polymeric since they allow reduction polymer’s viscosity or assist with dispersion fillers into polymer matrix. However, incorrect removal solvent affects both physical chemical ...

Semi-analytical solutions for vibration analysis of nonlocal piezoelectric Kirchhoff plates resting on viscoelastic foundation with arbitrary boundary conditions are derived by developing Galerkin strip distributed transfer function method. Based on the nonlocal elasticity theory for piezoelectric materials and Hamilton's principle, the governing equations of motion and boundary conditions are ...

The investigation of an alternate approach to nondestructive, nanoscale mechanical imaging for IC interconnect structures is reported. This approach utilizes a heterodyne interferometer based on a scanning probe microscope, also referred to as heterodyne force microscopy (HFM). This interferometer is sensitive to the relative phase difference of the two ultrasonic excitations due to spatial var...

In this article, bending, buckling, and free vibration of viscoelastic sandwich plate with carbon nanotubes reinforced composite facesheets and an isotropic homogeneous core on viscoelastic foundation are presented using a new first order shear deformation theory. According to this theory, the number of unknown’s parameters and governing equations are reduced and also the using of shear correct...

In this paper, the dynamic response of a viscoelastic beam subjected to a moving distributed load has been studied. The viscoelastic properties of the beam have been considered as linear standard model in shear and incompressible in bulk. The stress components have been separated to the shear and dilatation components and as a result the governing equations in viscoelastic form has been obtaine...
