Journal ArticleDOI
Kelvin-Voigt versus fractional derivative model as constitutive relations for viscoelastic materials
TL;DR: In this paper, three simple constitutive relationships for application to viscoelastic materials are studied for both a rubbery and a glassy visco-elastic material are fit by the three schemes.
Journal ArticleDOI
Numerical application of fractional derivative model constitutive relations for viscoelastic materials
TL;DR: In this article, a differential equation describing the motion of a viscoelastic bar is developed and studied, where the bar material is modeled using a fractional derivative based constitutive relationship.
Journal ArticleDOI
Sensitivity analysis of a wing aeroelastic response
TL;DR: In this article, a shape-sensitivity analysis of wing aeroelastic response proceeds from aero-linear response sensitivities obtained on the basis of the aerodynamic performance valid for high aspect ratio wings in subsonic, subcritical flow.
Journal ArticleDOI
Viscoelastic material response with a fractional-derivative constitutive model
TL;DR: In this article, a rubber coupon is modeled as a viscoelastic material by a fractional-derivative constitutive law to capture the material behavior over a broad frequency range.
Proceedings ArticleDOI
Integration of high fidelity structural analysis into parallel multidisciplinary aircraft analysis
TL;DR: A high fidelity parallel static structural analysis capability is created and interfaced to the multidisciplinary analysis package ENSAERO-MPI of Ames Research Center to more accurately modeled full aircraft structures using the new finite element capability.
