Comparison of Relaxation Modulus Converted from Frequency- and Time-Dependent Viscoelastic Functions through Numerical Methods

open access: yesApplied Sciences, 2018
Due to the difficulty of obtaining relaxation modulus directly from experiments, many interconversion methods from other viscoelastic functions to relaxation modulus were developed in previous years.

Interconversion of Prony series for relaxation and creep [PDF]

open access: yes, 2015
Various algorithms have been proposed to solve the interconversion equation of linear viscoelasticity when Prony series are used for the relaxation and creep moduli, G(t) and J(t).

The viscoelastic behavior of a composite in a thermal environment [PDF]

open access: yes
A proposed method for the accelerated predictions of modulus and life times for time dependent polymer matrix composite laminates is presented. The method, based on the time temperature superposition principle and lamination theory, is described in ...

A Compact Thermal Heat Switch for Cryogenic Space Applications Operating near 100 K

open access: yes, 2013
A thermal heat switch has been developed intended for cryogenic space applications operating around 100 K. The switch was designed to separate two pulse tube cold heads that cool a common focal plane array. Two cold heads are used for redundancy reasons,

Generalized Kelvin–Voigt Creep Model in Fractal Space–Time

open access: yesMathematics
In this paper, we study the creep phenomena for self-similar models of viscoelastic materials and derive a generalization of the Kelvin–Voigt model in the framework of fractal continuum calculus. Creep compliance for the Kelvin–Voigt model is extended to

DESIGN AND MANUFACTURING OF PROSTHETIC BELOW KNEE SOCKET BY MODULAR SOCKWT SYSTEM

open access: yesJournal of Engineering and Sustainable Development, 2016
The large numbers of terrorist attacks and the difficulty of the situations in Iraq led to the rise of the amputees’ numbers. However, typically 80% of the amputations are trans-tibial (below knee (BK) lower limb amputations). This research included the

Experiment and fractional derivative rheological modeling of the shear creep of HFRP overlap joints under dry and moist environments

open access: yes工程科学学报, 2017
The long-term performance of overlap adhesion, one of the major joint technologies of FRP, is key to its practical engineering application. Experiments on the creep behaviors of the double lap joint of a hybrid FRP (HFRP) were conducted.
