Abstract

•Hyperelastic characterisation requires multiaxial test data –uniaxial tension, pure shear and equibiaxial tension
•To increase the efficiency of material characterisation, a novel, inhomogeneous experiment is introduced utilising finite element optimisation
•No-slip compression test data is compared to an equivalent finite element model to optimise the coefficients of several material models
•Autonomous investigation of method through Finite Element Analysis (FEA)
•8-chain, Yeoh and Ogden-3 models were investigated; 8-chain and Yeoh are suitable for this method but Ogden-3 is not
•Combining with uniaxial test data enables an improved fit to test data
