Abstract The low-quality factor is a key bottleneck for the engineering and commercial application of graphene nanoelectromechanical resonators at room temperature. hypothesis in dissipation dominated by ohmic loss difficult to cover this phenomenon. Mechanical may still be on list main causes quality stress-modulation characteristics resonators. dilution theory reveals intrinsic energy mechani...

The reversible behaviour of metals at low applied stresses is more complex than the generally assumed linear behaviour. This primarily because nature dislocation motion leading to a strain contribution known as anelasticity. work aims investigate (a) quantification structures in industrial grade stainless steels, (b) unloading behaviour, and (c) fundamentals mechanical occurring below yield str...

The dynamic-mechanical response of flexible polymer networks is studied in the framework of tube model, in the limit of small affine deformations, using the approach based on Rayleighian dissipation function. The dynamic complex modulus G∗(ω) is calculated from the analysis of a network strand relaxation to the new equilibrium conformation around the distorted primitive path. Chain equilibratio...

This work presents and analyzes a collection of finite element procedures for the simulation of wave propagation in a porous medium composed of two weakly coupled solids saturated by a single-phase fluid. The equations of motion, formulated in the space-frequency domain, include dissipation due to viscous interaction between the fluid and solid phases with a correction factor in the high-freque...

Surface displacement and self-attraction loading (SAL) elevation induced by ocean tides are known to be affected material properties of the solid Earth. Recent studies have shown that, in addition elasticity, anelasticity considerably impacts surface displacements due tide (OTL). We employ consistent 3D seismic elastic attenuation tomography models construct anelastic earth models, derive corre...
