The seminar usually takes place on Thursdays from 4pm to 5pm in room ADB-1020
of the School of Mathematics, Statistcs and Applied Mathematics, which is located
Áras de Brún (Block C).
The talks are directed towards a general mathematical audience and everyone interested is very welcome to attend. Tea/coffee/biscuits/cake will be available in the ground floor research room (ADB-G022) 30 minutes before the seminar starts.
A list of seminars from the 2014/2015 academic year are also available.
Abstracts when available can be obtained by rolling the mouse over a title. Clicking a title sometimes provides a longer version of the talk in PDF format.

|A unified theoretical structure for modeling interstitial growth and muscle activation in soft tissues The objective of this paper is to develop a new unified theoretical structure for modeling interstitial growth and muscle activation in soft tissues. The model assumes a simple continuum with a single velocity field. In contrast with many other formulations, evolution equations are proposed directly for a scalar measure of elastic dilatation and a tensorial measure of elastic distortional deformation. The evolution equation for elastic dilatation includes a rate of mass supply or removal that controls volumetric growth and causes the elastic dilatation to evolve towards its homeostatic value. Similarly, the evolution equation for elastic distortional deformation includes a rate of growth that causes the elastic distortional deformation tensor to evolve towards its homeostatic value. Specific forms for these inelastic rates of growth and the associated homeostatic values have been considered for volumetric, area and fiber growth processes, as well as for muscle activation. Since the rate of growth appears in the evolution equations and not a growth tensor it is possible to model the combined effects of multiple growth and muscle activation mechanisms simultaneously. Also, robust, strongly objective, numerical algorithms have been developed to integrate the evolution equations.||Michel Destrade|
