DIGITAL SPECKLE PATTERN INTERFEROMETRY IN BIOMECHANICS: IN SITU INVERSE ANALYSIS ON BIRDS BEAKS TO OBTAIN ELASTIC MODULUS OF THE BONY CORE AND THE KERATIN LAYER

J. Soons, J. Dirckx
Abstract:
The beak of finches is a very important example in evolution theory, and yet not fully understood. Furthermore, it is also fascinating from a mechanical point of view. In this paper we will use digital speckle pattern interferometry to obtain the displacement of the upper beak while loaded. Next, a finite element model is used in an inverse analysis, resulting in the modulus of the bony core and the keratin layer of this complex sample.
