Abstract Scope |
A methodology is shown for predicting the time-dependent reliability (probability of survival) of bioceramic components subjected to transient load histories. This methodology is based on the Weibull distribution to model stochastic strength and a power law that models subcritical crack growth. Changes in material response that can occur with time are included in the model. This capability was coded and is available in the probabilistic design code CARES/Life (Ceramic Analysis and Reliability Evaluation of Structures) which was originally developed at NASA. The capability to model the effects of proof testing Bioceramics to ensure their reliability during their service life was also incorporated in the code. CARES/Life interfaces with commercially available finite element analysis codes to predict the reliability of Bioceramic components. Dental examples are provided to demonstrate the methodology. |
