摘要：

Hyperelastic and hyperfoam constitutive models are calibrated for rigid polyurethane (PU) foam exhibiting the characteristics of both soft foam and rubber. Test data from uniaxial and volumetric compression are used for calibration of the models with the goal of simulating a compressive-loading event (a hemispherical indentation). When the indentation event is simulated using the calibrated models via finite element analysis, both models moderately predict the experimentally determined load displacement curve: the fitting errors of the two models were 13.6% and 11.5%, respectively. The applicability and limitations of the models for describing the indentation behavior of the rigid PU foam are discussed.
