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

open access: yesMaterials 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

open access: yesEarth, 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.

Viscoelastic and Poroelastic Relaxations of Soft Solid Surfaces [PDF]

open access: yesPhysical Review Letters, 2020
Understanding surface mechanics of soft solids, such as soft polymeric gels, is crucial in many engineering processes, such as dynamic wetting and adhesive failure. In these situations, a combination of capillary and elastic forces drives the motion, which is balanced by dissipative mechanisms to determine the rate.

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

open access: yesNihon 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 ...

Aftershock production rate of driven viscoelastic interfaces [PDF]

open access: yes, 2014
We study analytically and by numerical simulations the statistics of the aftershocks generated after large avalanches in models of interface depinning that include viscoelastic relaxation effects.

The effects of rheological layering on post-seismic deformation [PDF]

open access: yes, 2006
We examine the effects of rheological layering on post-seismic deformation using models of an elastic layer over a viscoelastic layer and a viscoelastic half-space. We extend a general linear viscoelastic theory we have previously proposed to models with

Remodeling by fibroblasts alters the rate-dependent mechanical properties of collagen [PDF]

open access: yes, 2016
The ways that fibroblasts remodel their environment are central to wound healing, development of musculoskeletal tissues, and progression of pathologies such as fibrosis.

Stress concentration in nonlinear viscoelastic composites

open access: yesMechanics and Advanced Technologies, 2017
A nonlinear viscoelastic problem of the mechanics of composites is solved within the framework of a second-order nonlinear theory. A viscoelastic functional is used to construct general defining relations.

Fractional viscoelastic models for the estimation of the frequency response of rubber bushings based on relaxation tests

open access: yesResults in Engineering, 2023
Estimation of the viscoelastic properties of rubber bushings at very high frequencies (up to 2 kHz) is a challenge for many damping component manufacturers in the design stage of a quality monitoring procedure.
