The foot's response to load during weightbearing is investigated using finite element stress analysis of a two-dimensional model. The analysis predicts the stress states within the plantar aspect tissue during a variety of shoe conditions. Shoe soles with a range of elastic properties are modeled in an attempt to find a shoe sole that minimizes peak stresses within the foot's soft tissue. This presently simplified and idealized model of the foot and shoe during mid-stance demonstrates significant dependency of stress development within the tissue on shoe elastic properties. These results would seem to justify further more detailed and realistic modeling of shoeing mechanics, and systematic efforts to correlate physical measurements and clinical experience with the trends indicated by finite element analyses.
采用二维模型的有限元应力分析方法，研究了负重过程中足部对负荷的反应。该分析预测了在各种鞋类条件下足底组织内的应力状态。对具有一系列弹性特性的鞋底进行建模，试图找到一种能使足部软组织内峰值应力最小化的鞋底。这种目前简化和理想化的足部与鞋类在站立中期的模型表明，组织内应力发展对鞋类弹性特性有显著依赖性。这些结果似乎证明有必要对制鞋力学进行更详细和现实的建模，并系统地努力将物理测量和临床经验与有限元分析所示趋势相关联。
