Abstract
Giraffe's long neck is subjected to large moment and under severe mechanical condition. The giraffe's neck is interesting structure in mechanical viewpoint, because it achieve a both of high strength and flexibility. Purpose of this study is to investigate how does giraffe's neck adapts to the severe condition. In this study, we created finite-element models include bone and ligament and muscle on giraffe's neck and analyzed about displacement and stress. In addition we created models represented some postures of drinking water and. We gave muscle force to muscle models by equivalent heat contraction. As a result, we confirmed that the model can keep their posture stably with muscle forces, and cervical bone stress is also under feasible region.
