“…Also authors of work [23] applied FeM to determine abrasive wear of UHMWPe for acetabular cup -head from CoCr alloy at different tilt angles. In turn, in the paper [24] scientists have showed results of numerical tests for implants with standard holes, which fulfill strength requirements at maximum strains and assumed load system, whereas work [25] has been concerned research results of pressure and cup deformation, which was carried out at different friction conditions (wet and dry) and for two geometric configurations.…”

The article has been devoted to issues connected with the alloplasty and hip joint endoprostheses, that elements are being developed, which is supported by strength, tribological tests on used biomaterials, incl. polyethylene or computer modelling based on e.g. finite element method (FeM). In this paper, the results of research on the impact of the material articulations of the system head -acetabular and friction conditions on strength parameters of polyethylene components in the hip joint endoprosthesis. Numerical analysis of this friction node was carried out, using the AdINA System computer program and the simulations were performed at various friction conditions for metal/ polyethylene and ceramic/ polyethylene articulations with various UHMWPe modifications. The simulations results have shown the influence of tested material associations and friction conditions on parameters related to the strength of polyethylene cups, i.e. their displacements, stresses and deformations.
