摘要：Mandibular fracture is increasingly treated with fixing plate instead of wire sawing in order to retrieve jaw functionality. Fixing plate need to as light as possible, yet the long fatigue life is a must. Non-parametric optimization-based design has been implemented in this work to achieve long fatigue life. Mandibular has been simulated using finite element method from computed tomography scan. In order to achieve long fatigue life plate with minimal weight, cascade Non-parametric optimization modeling is implemented in two stages. First stage is stress based optimization. The second stage is fatigue based stress optimization. In the first stage, the comparison between shape and topology optimization. Fist cascade model (Stress based topology-Fatigue based optimization) gave the better results in term of weight reduction (45%) while the second cascade model (Stress based shape-fatigue based optimization) doubled the fatigue life.
