methodology and those obtained with commercial software (differences <5%) indicate a successful implementation of the hyper-elastic model. In addition, the ability of the methodology to predict similar stresses with a nodal distribution 14 times coarser confirms the advantage of the NNRPIM. Consequently, this methodology can be used as a basis for further developments.
