本文是根據作者以往的研究成果所所研發出的一種人體脊椎多孔彈性三維有限元素改良型模式。本模式主要是用於了解人體脊椎的力學行為。在這各特殊的改良型模式上考慮及(1)不同材料組織間之界面元素之涵蓋(2)具有斜式接觸面之平關節,以及(3)伸張性韌帶結構。為了考慮韌帶的伸張特性,本研究採用反覆是計算過程,來解決這種伸張力學行為。本報告之目的是以改進之模式與原型比較,所以只提供靜態分析結果。分析結果則包含了脊椎的變形態及分佈於人體脊椎上各種應力。本研究所改進之人體脊椎模式能提供許多比原型模式更有效、更有意義的醫學參考資料。
Here, referred to authors previous work, an improved three-dimensional poroelastic finite element model of the human spine is proposed for understanding of the mechanical behaviors occurred in the spine. On this particular, improved model, (1) interface elements are implemented between elements with different materials, (2) facet joints with inclined contact nodes and (3) tensile ligaments are included in the current model. Iteration of calculations has thus been made for the correction of the mechanical activities of the tensile ligaments. For purpose of comparison with results from the prototype developed before, long-time creep predictions (elastic, static) are discussed here. Numerical results include the deformed shapes and various stress distributions appeared in the spine. The improved model is more applicable and more significant than the prototype.
