We seek to develop the scientific basis for the interpretation of the results of "deep" indentation testing of non-linear elastic (hyper-elastic) materials. Simple tests (such as indentation) produce complex strain fields. Interpretation of the resulting data in terms of stiffness, for example, requires a complex model of the deformation process that can be utilised to link the observed behaviour to the basic properties of interest. This project is dedicated to an understanding of the complex deformation associated with large strain indentation of hyper-elastic materials and structures, development of finite element based models for this deformation and creation of techniques for interpretation of the results of such indentation tests.Read moreRead less
