Indentation method for dertermining the constitutive parameters of hyperelastic soft materials

摘要

The spherical indentation of hyperelastic soft materials (e.g.elastomeric materials and biologicalsoft tissues) is explored.For four widely used hyperelastic constititute material models,including neo-Hookean,Mooney-Rivlin,Fung,and Arruda-Boyce models,the relations between theindentation loads at various given indentation depths and the material properties are establishedby using dimensional analysis and finite element computations.
