Abstract:

Many natural structures are made of soft tissue that undergoes active growth. Non-uniform growth of thin sheets can lead to the formation of elaborate three-dimensional configurations and to induce non-trivial shape transformations. In particular, complicated configurations appear in thin sheets when growth leads to geometrical frustration.

I will present examples of different types of systems and discuss different types of self shaping principles, together with the theoretical framework of incompatible elasticity which is used to study such systems. Experimental methods for the construction of "programmed" responsive sheets will be reviewed and the connection of the topic to chemical and biological systems, as well as to design and art, will be presented.
