本論文以準靜態(Quasi-Static)模擬步態反應分析鞋墊與鞋底膠對足部組織的影響，建構完整的3D實體模型，用以分析步態反應，因骨頭與足部軟組織中的軟骨與筋膜等楊氏模數相差1000倍以上，故在有限元素模型上將腳骨設定剛體，突破以前學者們在文獻中的設定，再探究與比較線性與非線性材料對於足部軟組織與足底筋膜的影響，以上三大主題為本論文最主要的目的。分析結果顯示，足底壓力根據足底步進狀態與地面所夾不同角度時，壓力分佈會有不同，但集中的位置仍然在蹠骨 (Metatarsal)及足跟(Hee)等區塊。本論文透過完整的分析過程，確信以剛體模擬腳骨進行分析是可行，且能縮短分析時間與提高收斂性。本論文亦探討線性與非線性材料對於足部軟組織與足底筋膜的影響，結果顯示，對於準靜態(Quasi-Static)分析，線性材料與非線性材料並無太大差別，從材料特性曲線上便可得知，故足部軟組織與足底筋膜只需以線性材料模擬即可，並不需考慮非線性材料的影響，由此結果可推得在靜態的分析時，更無須考量非線性材料，不過此論點只適合靜態與準靜態分析，當考慮動態分析時，則須對材料重新定義。

In this study, a 3D solid model of right-foot was created and quasi-static analysis of gait response was used to simulate the foot tissues for insole and outsole by ANSYS12.0. The Young’s modulus of bone was more 1,000 times than cartilage and fascia in foot tissues, so the bone could be set as rigid in finite element model while simulating in ANSYS. Moreover, linear and nonlinear material for soft tissue and fascia were compared. Above three subjects were the main purposes in this study. According to the results, distribution of plantar pressure was different from the angles of gait response, but the position of stress concentration was occurred on metatarsal and heel. Moreover, the simulation in this study could reduce computing time and improved convergence by setting bone as rigid. For quasi-static analysis in this study, there was less difference with linear and nonlinear material which could be learned from material properties of the curve. Hence, soft tissue and fascia could be simulated with linear material in static analysis. However, the concept was only appropriate for static and quasi-static analysis and it should be reconsidered in dynamic analysis.
