| Abstract | ||
| This study contains a comparative analysis of two polymers: PEEK and UHMWPE. A stress distribution pattern in a knee joint endoprosthesis insert was determined for both materials. A numerical model of the insert generated by means of the SOLIDWORKS software was used in calculations. For the purpose of the calculations it was assumed that the insert is loaded consistently and symmetrically, and the value of the load applied was determined for a person of a total weight of 120 kg. | ||
