There is evidence that damage, viscoelastic stiffness properties, and postyield mechanical properties are related in bone tissue. Our objective was to test whether presence of a flaw would have an influence on the apparent viscoelastic properties of bone. Examining the effect of flaw orientation on apparent viscoelastic properties and utilization of dynamic mechanical analysis (DMA) as a nondes...

one of the most important factors that affect tire friction is surface roughness, which determines the size of the real contact area, real pressure distribution on the contact interface, and scales of mechanical engagement between viscoelastic rubber and a rough substrate. the need to predict coefficient of friction (cof) for rubber on rough surfaces for applications such as traction of tires o...

In this paper, we consider a contact problem between viscoelastic Bresse beam and deformable obstacle. The well-known normal compliance condition is used to model the contact. existence of unique solution continuous proved using Faedo-Galerkin method. An exponential decay property also obtained defining an adequate Liapunov function. Then, finite element method implicit Euler scheme, approximat...

This study is concerned to check the validity and applicability of a five parameter viscoelastic model for harmonic wave propagating in the non-homogeneous viscoelastic rods of varying density. The constitutive relation for five parameter model is first developed and validity of these relations is checked. The non-homogeneous viscoelastic rods are assumed to be initially unstressed and at rest....

Magnetorheological fluid (MRF) sandwich beams belong to a class of adaptive that consists MRF sandwiched between two or more face layers and have great prospective for use in semi-active control beam vibrations due their superior vibration suppression capabilities. The composition has strong influence on the properties hence affects characteristics beam. In this work, six samples (MRFs) compose...

The purpose of this paper is to analysis the viscoelastic models under dynamic loading. A five-parameter model is chosen for study exhibits elastic, viscous, and retarded elastic response to shearing stress. The viscoelastic specimen is chosen which closely approximates the actual behavior of a polymer. The module of elasticity and viscosity coefficients are assumed to be space dependent i.e. f...
