Nonlinear vibration and dynamics of ceramic on ceramic artificial hip joints: a spatial multibody modelling
TL;DR: In this paper, a spatial multibody dynamic hip model was developed, using a friction-velocity constitutive law combined with a Hertzian contact model, and the physiological three-dimensional rotation angles and forces were taken into account to calculate tangential and normal contact forces, respectively.
Micro-CT based finite element modelling and experimental characterization of the compressive mechanical properties of 3-D zirconia scaffolds for bone tissue engineering.
Ehsan Askari,Ibrahim Fatih Cengiz,J. L. Alves,Bruno Henriques,Paulo Flores,M.C. Fredel,Rui L. Reis,J. M. Oliveira,Filipe Samuel Silva,J. Mesquita-Guimarães +9 more
TL;DR: A micro-CT based finite element model that allows characterizing the mechanical property of zirconia foams for bone tissue engineering and a deep insight into the association of macroscopic behaviour of the scaffold to microscopic features can be gained.

A review of squeaking in ceramic total hip prostheses
TL;DR: This article summarizes the recent available literature on ceramic-on-ceramic hip prostheses to provide a platform for future research and development and describes high wear rates and ceramic liner fracture as viable consequences of hip squeaking.

Coupled vibration of a partially fluid-filled cylindrical container with a cylindrical internal body
Ehsan Askari,Farhang Daneshmand +1 more
TL;DR: In this article, the effects of a rigid internal body on the coupled vibration of a partially fluid-filled cylindrical container are investigated and the results from the proposed method are in good agreement with experimental and numerical solutions available in the literature.

Coupling multi-body dynamics and fluid dynamics to model lubricated spherical joints
Ehsan Askari,Paulo Flores +1 more
TL;DR: In this paper, a new approach of coupling multibody dynamics and fluid dynamics is developed to model hydrodynamic lubrication of spherical clearance joints with thin fluid film and relative multidirectional motion.
