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.
