Viscoelastic Relaxation Modulus Characterization Using Prony Series [PDF]
Latin American Journal of Solids and Structures, 2015 The mechanical behavior of viscoelastic materials is influenced, among other factors, by parameters like time and temperature. The present paper proposes a methodology for a thermorheologically and piezorheologically simple characterization of ...

Simulation of relaxation time and storage modulus for carbon nanotubes-based nanocomposites
Journal of Materials Research and Technology, 2021 This paper develops two equations for relaxation time and storage modulus of biopolymer nanocomposites at unlike frequency ranges. The relaxation time is correlated to zero complex viscosity, yield stress, K constant and power-law index. In addition, the

Simple average expression for shear-stress relaxation modulus [PDF]
Physical Review E, 2016 Focusing on isotropic elastic networks we propose a novel simple-average expression $G(t) = _A - h(t)$ for the computational determination of the shear-stress relaxation modulus $G(t)$ of a classical elastic solid or fluid and its equilibrium modulus $\G_{eq} = \lim_{t \to \infty} G(t)$.

Constant Modulus Shaped Beam Synthesis via Convex Relaxation [PDF]
IEEE Antennas and Wireless Propagation Letters, 2017 Constant modulus shaped beam synthesis is widely employed in multiple-input–multiple-output (MIMO) radar systems and MIMO wireless communication systems to improve the effective power gain by using only phase adjustment. To achieve the maximum beam gain, we formulate a new optimization problem to maximize the main lobe gain and also properly suppress ...

Young's modulus and ?-relaxation of amorphous polymers [PDF]
Journal de Physique III, 1991 The mechanical behaviour of polymers have been studied as a function of time and temperature. The influence of a critical temperature or critical strain rate have been pointed out which may be related to relaxation phenomena. This study, carried out on Poly Methyl Methacrylate, shows that this relaxation phenomena can be associated to the β-relaxation.
