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
