Journal ArticleDOI
An analytical poroelastic model for ultrasound elastography imaging of tumors.
TL;DR: The availability of the analytical model and solutions presented in this paper may be useful to estimate diagnostically relevant poroelastic parameters such as interstitial permeability and fluid pressure, and, in general, for a better interpretation of clinically-relevant ultrasound elastography results.
Journal ArticleDOI
A mixed computational algorithm for plane elastic contact problems—I. formulation
Paul R. Heyliger,J. N. Reddy +1 more
TL;DR: In this paper, a mixed variational statement and corresponding finite element model are developed for an arbitrary plane body undergoing large deformations (i.e. large displacements, large rotations and small strains) under external loads using the updated Lagrangian formulation.
Journal ArticleDOI
Dynamic analysis of three-dimensional high-speed train-track model using moving element method:
TL;DR: The moving element method is extended to establish the coupling formulations of the mass, damping, and stiffness matrices in vertical and lateral directions, where the element matrices are formulated based on a convected coordinate system attached to the moving vehicle.
Journal ArticleDOI
Nonlinear Deflection Control of Laminated Plates Using Third-Order Shear Deformation Theory
S.J. Lee,J. N. Reddy +1 more
TL;DR: In this paper, the effects of shear deformation and geometric nonlinearity on the bending and transient response are investigated using the finite element method, where magnetostrictive material, Terfenol-D, layers are used to actively control the deflection via simple negative velocity feedback control in a closed loop.
Journal ArticleDOI
Coupled polynomial field approach for elimination of flexure and torsion locking phenomena in the Timoshenko and Euler-Bernoulli curved beam elements
TL;DR: In this article, a locking-free curved beam finite element model was developed using coupled polynomial displacement field interpolations to eliminate curvature related locking effects in the out-of-plane deformation of Timoshenko and Euler-Bernoulli curved beam elements.
