Strain rate sensitivity of the commercial aluminum alloy AA5182-O
R. C. Picu,Gabriela Vincze,Fahrettin Ozturk,José Grácio,Frédéric Barlat,Frédéric Barlat,Antoinette M. Maniatty +6 more
TL;DR: In this article, the effect of dynamic strain aging on ductility and strain hardening of commercial aluminum alloy AA5182-O was investigated at temperatures ranging from −120 to 150 ◦ C and strain rates from 10 −6 to 10 −1 s −1.
Journal ArticleDOI
A stabilized mixed finite element method for finite elasticity.: Formulation for linear displacement and pressure interpolation
TL;DR: In this article, a stabilized mixed finite element method for finite elasticity is presented, which circumvents the fulfillment of the Ladyzenskaya-Babuska-Brezzi condition by adding meshdependent terms, which are functions of the residuals of the Euler-Lagrange equations, to the usual Galerkin method.
Journal ArticleDOI
Shear modulus reconstruction in dynamic elastography: time harmonic case
TL;DR: This paper presents a direct inversion approach for reconstructing the elastic shear modulus in soft tissue from dynamic measurements of the interior displacement field during time harmonic excitation using a finite element discretization of the governing equations as a basis.
Journal ArticleDOI
Finite Element Analysis of Some Inverse Elasticity Problems
TL;DR: In this article, the boundary tractions and displacements in an elastically deformed two-dimensional body are calculated using experimentally determined or specified displacements or strains at a finite number of internal points in the body.
Journal ArticleDOI
A geometric approach to modeling microstructurally small fatigue crack formation: I. Probabilistic simulation of constituent particle cracking in AA 7075-T651
J. E. Bozek,Jacob D. Hochhalter,M G Veilleux,Mu Liu,Gerd Heber,S D Sintay,Anthony D. Rollett,David John Littlewood,Antoinette M. Maniatty,Hasso Weiland,Robert J. Christ,J Payne,G Welsh,D G Harlow,Paul A. Wawrzynek,Anthony R. Ingraffea +15 more
TL;DR: In this article, three-dimensional elasto-viscoplastic finite element analyses are performed to develop a response surface for the tensile stress in the particle as a function of the strain level surrounding the particle, parent grain orientation and particle aspect ratio.
