Viscoelastic Finite Line Contact of Thin Bonded Layered Solids of Low Elastic Modulus

Applied Sciences, 2020
A new finite element-based contact mechanics analysis of layered viscoelastic solids of low elastic modulus is presented. The methodology is based on the Maxwell viscoelastic element, with stress relaxation taken into account by the Prony series ...

Viscoelastic Characterization of Parasagittal Bridging Veins and Implications for Traumatic Brain Injury: A Pilot Study

Bioengineering, 2021
Many previous studies on the mechanical properties of Parasagittal Bridging Veins (PSBVs) found that strain rate had a significant effect on some mechanical properties, but did not extensively study the viscoelastic effects, which are difficult to detect

A numerical approach to characterize the compression and relaxation behavior of uncured prepreg laminates in the process of hot press-forming

Materials Research Express, 2022
In the pre-forming process of uncured prepreg laminates with hot press, the compaction stress is an important parameter that affects the performance and quality of the final product.

Probing time-dependent afterslip and viscoelastic relaxation following the 2015 Mw7.8 Gorkha earthquake based on the 3-D finite-element model

Earth, Planets and Space, 2020
We analyzed daily displacement time series from 34 continuous GPS stations in Nepal and 5 continuous GPS stations in South Tibet, China, and extracted the first 4.8 years of postseismic motion after the 2015 Mw7.8 Gorkha earthquake.

Computational study on temperature-dependencies of relaxation and elastic properties in anisotropic viscoelastic constitutive law for fiber-reinforced thermoplastic resin

Nihon Kikai Gakkai ronbunshu, 2019
With use of the numerical material testing (NMT) approach based on homogenization theory, a time-temperature reduction law is proposed for both relaxation and elastic properties in the orthotropic viscoelastic constitutive equation, which is supposed to ...

Gravitational viscoelastic relaxation of eccentrically nested spheres [PDF]

Geophysical Journal International, 1999
SUMMARY We present a semi-analytical solution to the 2-D forward modelling of viscoelastic relaxation in a heterogeneous model consisting of eccentrically nested spheres. Several numerical methods for 2-D and 3-D viscoelastic relaxation modelling have been applied recently, including finite-element and spectral-finite-diVerence schemes.
