摘要：Polyurethane (PU) foam is a material often ud in biomechanical experiments and demands for the definition of crushable foam plasticity (CFP) in numerical simulations of the primary stability and deformation of implants, to describe the crushing behaviour appropriately. Material data of PU foams with five different densities (10-40 pounds per cubic foot were ascertained experimentally in uniaxial compression test and ud to calibrate CFP models for finite element modelling. Additionally, experimental and numerical deformation, push-out and
lever-out tests of press-fit acetabular cups were carried out to asss the influence
not until
of the chon material definition (linear elastic and CFP) on the numerical results. Comparison of the experimentally and numerically determined force-displacement curves of the uniaxial compression test
