Abstract

This talk will present a computational optimization method which can be used to find ways to deform elastic plates into specific desired target shapes. Beginning with flat plates undergoing inhomogeneous growth -- for example bimetallic strips and potato chips -- we first derive the equations governing the system and develop the
optimization procedure that would identify the growth fields necessary to grow a plate into a desired target shape. Simple numerical calculations will be presented. Finally, possible extensions of the technique will be discussed, including the possibility of finding the edge displacements which would cause a flat plate to attain a given target shape.
