Computer Simulation of Tissue and Muscle Behaviour

Cartilage Deformation

Computational methods and software are developed for simulation of a large number of natural processes. For example cartilage response subjected to general loading conditions. Cartilage is considered as a porous deformable medium filed with fluid. The coupled solid-fluid model includes swelling pressure effects through water content, ion concentration or electro-kinetic coupling.

The software can be used in cartilage mechanics in general, but specific features for particular problems are developed.

• Viscoelastic behaviour and creep, 3D model of cartilage
• Swelling effect: water content, ion concentration, electro-kinetic coupling
• Modelling of passive and active conditions, activation function

Applications:

• Analysis of work and sporting activities to minimise damage.
• the effect of surgery - analysing how removal or fusion techniques will effect other working parts.
• The effect of drug treatments to remove swelling.

A specific software for automatic generation of input data and the analysis results is in the development phase.
