| description | This paper presents two multiaxial fatigue life prediction models applied to a commercial dental
implant. One model is called Variable Initiation Length Model and takes into account both the crack initiation
and propagation phases. The second model combines the Theory of Critical Distance with a critical plane
damage model to characterise the initiation and initial propagation of micro/meso cracks in the material. This
paper discusses which material properties are necessary for the implementation of these models and how to
obtain them in the laboratory from simple test specimens. It also describes the FE models developed for the
stress/strain and stress intensity factor characterisation in the implant.
The results of applying both life prediction models are compared with experimental results arising from the
application of ISO-14801 standard to a commercial dental implant. |
