Modelling of the nature is developed at three levels. At the first level, a relatively simple approach is used to imitate a natural function such as healing human skin, which can then be used for healing a crack. At the second level, various models are created to produce a multifunctional component, for example, a biomimetic of shark skin, which can be adopted for a swimming suit that gives an increase in the swimming speed. At the same time the textile would be capable of repairing itself after a scratch or a puncture. At the third level, a model will be based on a more complex design. Most of the models developed try to predict and optimise self-healing behaviour of materials at the first level. Some of the most interesting work in that area is reviewed in Sections 3.1 and 3.2 and gives an example of such modelling with finite element analysis (FEA). No work has been reported on the second level models. Recently several approaches at third level modelling have been proposed and developed. A brief summary of these models is reviewed in Section 3.3.
