Characterisation of Elastic and Acoustic Properties of an Agar-Based Tissue Mimicking Material

ANNALS OF BIOMEDICAL ENGINEERING, 43(10), 2587–2596.

By: M. Brewin *, M. Birch*, D. Mehta*, J. Reeves *, S. Shaw *, C. Kruse *, J. Whiteman*, S. Hu n ...

author keywords: Acoustic properties; Acoustic localisation; Coronary artery; Elastic moduli; Poisson's ratio; Shear modulus; Shear wave; Stenosis; Tissue mimicking material; Viscoelasticity
MeSH headings : Agar / chemistry; Animals; Biomimetic Materials / chemistry; Coronary Stenosis / diagnostic imaging; Coronary Stenosis / physiopathology; Elastic Modulus; Humans; Phantoms, Imaging; Ultrasonography
TL;DR: Measurements are reported for an agar-based tissue mimicking material of the shear wave propagation velocity, attenuation and viscoelastic constants, together with one dimensional quasi-static elastic moduli and Poisson’s ratio to provide baseline data required for the computational modelling of wave propagation in a phantom.

2014 journal article

High-order space-time finite element schemes for acoustic and viscodynamic wave equations with temporal decoupling

INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING, 98(2), 131–156.

By: H. Banks n, M. Birch*, M. Brewin *, S. Greenwald *, S. Hu n, Z. Kenz n, C. Kruse *, M. Maischak*, S. Shaw *, J. Whiteman *

author keywords: viscoelasticity; high order methods; discontinuous Galerkin finite element method; spectral element method; space-time finite elements
TL;DR: This work revisits a method for temporally discontinuous Galerkin FEMs applied to a parabolic partial differential equation and applies this DG-in-time methodology, for the first time, to second-order wave equations including elastodynamics with and without Kelvin–Voigt and Maxwell–Zener viscoelasticity.
