About

Multi-scale modelling of solids is an area of increasing interest within the applied and computational mechanics community. Multi-scale concepts allow the development of new models to describe the constitutive behaviour of solids by including information at two or more physical scales. Development of models of this type, in particular with the use of computational homogenisation methods based on Finite Element procedures, is currently under way.

An application of particular interest is the modelling and simulation of biological tissues in general. Such materials posses in general intricate microstructures that lead to complex macroscopic behaviour. Multi-scale methods are currently being used in this context in the modelling of human artery constitutive response. Further use of multi-scale methodologies is being made in the modelling of polycrystalline metals as well as in heat conduction problems in general. New recent research directions in this field include the prediction of the sensitivity of macroscopic material properties to topological microstructural changes, calculated by means of the so-called topological derivative concept. Such procedures will lead in the near future to new techniques for microstrucural optimisation.

Computational multi-scale techniques lead to formidable tasks from the computing point of view. Therefore, the overall efficiency of the multi-scale framework needs to be optmised to allow its use in the solution of practical problems. In this context, computational techniques stemming from the expertise of this research group are under development, which so far have produced substantial reductions in computing time. Further developments are foreseen in the near future.

Taught Modules

EG-3067 Finite Elements for Civil Engineers

This module provides an introduction to the Finite Element Method of analysis. The material delivered in this module is of particular relevance to civil engineers, with focus on the analysis of structural mechanics and groundwater flow problems. Both theory and its application are covered, including elements of Matlab programming in this context and the use of commercial finite element software of widespread use in industry.
EG-M25 Advanced Structural Analysis

The module develops theory and associated solution techniques relevant to structural problems related to plates, shells and solid applications. The basic theoretical concepts are firstly introduced and the underlying governing equations then developed. The first topic considered is the elastic theory of plate bending, which is of fundamental importance in the design and analysis of a large class of engineering structures. This is followed by the limit analysis of plate structures, which is of prominence in reinforced concrete design. A central aspect of the course is the treatment of the membrane analysis of shell structures. Most shell structures operate by their resistance to membrane action, rather than bending, and the course develops solution procedures for a range of practical shell structure applications encountered in both civil and mechanical engineering environments. The course concludes by developing solution strategies for structures subjected to torsion, with particular emphasis placed on the analysis of thin walled structures, such as those encountered in bridge deck construction and aerospace applications.
