Abstract
The paper describes an experimental procedure to find the optimal values of the coefficients of the Yeoh hyperelastic material model for a resilient mounting element for marine diesel engines. The quasi-static implicit finite element simulation of the resilient mount deformation under an increasing load is matched with the force-displacement curve of the element acquired via laboratory tests. A response surface analysis is then performed to create a predictive model. This allows to find the best values of the Yeoh coefficients and assess their importance in the predictive equation. With a limited number of runs it is possible to obtain a finite element model that simulates accurately the static deformation of the resilient mounting element over the entire loading range.
