This article presents a very detailed study on the mechanical characterization of highly nonlinear material, immature equine zona pellucida (ZP) membrane. The ZP is modeled as visco-hyperelastic soft matter. Arruda–Boyce constitutive equation and two-term Prony series are identified most suitable models for describing hyperelastic viscous components, respectively, ZP’s response. Material proper...

Usually, the viscoelastic (VE) response of polymers for applications in composites is obtained uniaxial strainor stress-controlled tests. However, analyzing multimaterial structures by Finite Element Method (FEM) or other numerical analytical tools, a material model terms complete set compliance functions and/or relaxation required. In this paper, methodology and exact expressions calculating w...

This study considers the problem of numerical modeling PEEK product’s 3D printing using FDM technology. The aim is to verify adequacy use a thermoviscoelastic model for computations deposition process and develop an algorithm calculating this process. Prony used describe behavior material under study; temperature-time shift described by Williams–Landel–Ferry function (WLF). To obtain values con...

The occurrence of low-frequency electromechanical oscillations is a major problem in the effective operation power systems. scrutiny these provides substantial information about system stability and security. In this paper, new method introduced based on combination synchrosqueezed wavelet transform stochastic subspace identification (SSI) algorithm to investigate large-scale Then, estimated mo...

Generalized Langevin dynamics (GLD) arise in the modeling of a number of systems, ranging from structured fluids that exhibit a viscoelastic mechanical response, to biological systems, and other media that exhibit anomalous diffusive phenomena. Molecular dynamics (MD) simulations that include GLD in conjunction with external and/or pairwise forces require the development of numerical integrator...

The traditional infrastructure of power system industry is presently going through large amount of change that consensus over the improvement of power quality for fulfilling this requirement electronically automated devices having high sensitivity toward the disturbance in the power system signals are under the major consensus of research activities. The low power quality signal is responsible ...

We derive a new generalization of Prony’s method to reconstruct M-sparse expansions of (generalized) eigenfunctions of linear operators from only O(M) suitable values in a deterministic way. The proposed method covers the wellknown reconstruction methods for M-sparse sums of exponentials as well as for the interpolation of M-sparse polynomials by using special linear operators in C(R). Further,...
