| 摘 要： | 本文采用二维有限元,对下颌骨进行应力分析研究。提出2种模型、3种牙齿负载条件和3种咀嚼肌力分布。有限元分析和光弹实验比较,两种结果较为一致,大应力集中在下颌角髁突区、磨牙后区和负载作用的齿冠上。

| Abstract: | Two-dimensional finite element stress analyses were employed to study the human mandible. Two models, three teeth loading conditions and three distributions of masticatory muscles are presented. Finite element analyses are compared with photoelastic experiments to indicate correspondence between both results. High stress concentrates in the mandibular angle, condylar region, retromolar area and dental orown. |
