Long‐term stability and debonding of cementless implants
Year: 2021
Type: article
Abstract: This work presents a three‐dimensional FE frictional contact formulation with NURBS‐enriched contact elements for the debonding of partially osseointegrated, cementless implants. The contact model is based on a modified Coulomb's friction law [1] that can model the tangential debonding of partially osseointegrated implants. Here, a smooth transition function between the two friction coefficients is used to model the decrease of friction due to debonding of the implant. The model is applied to simulate the debonding of a hip implant to determine the influence of partial osseointegration on the stability of the implant.
