Bio-inspired materials


 In recent years, the investigation of new strategies inspired by nature for the development of more advanced materials has received considerable attention in scientific communities. By mimicking morphological patterns and natural mechanisms of interaction among basic constituents, scientists have found promising guidelines in the next generation of engineering materials.

 

Wood microstructure can be understood as the result of an optimisation process developed by nature over millions of years. One of its main features is its hierarchical nature distributed across multiple spatial scales. This important feature has been widely investigated over the last few years by means of multi-scale finite element models.

From an engineering point of view, one of the most important consequences in fully understanding the mechanical behaviour of wood and in general, natural materials, at several scale levels, is the inspiration of new strategies to design more advanced materials.
