Seminar - Giang Nguyen - Non-local constitutive modelling using damage and breakage mechanics
Wednesday 1 October 2008, 1.10 - 1.55 pm
Civil Engineering Lecture Theatre 3
It is well known that conventional continuum mechanics lacks a length scale and hence is inadequate to capture correctly the behaviour of solids/structures made of softening materials. To circumvent the problem, special treatments, called regularization techniques, need to be applied to the constitutive modelling as well as the numerical analysis. Different types of regularization, from simple (cohesive crack models, smeared crack models) to more advanced (nonlocal models), can be used. The presentation will give a brief overview about non-local models of integral type and their several aspects in the constitutive modelling using damage and breakage mechanics.
