糖尿病病人的足部與輔具之二維有限元素接觸應力分析
Abstract
The objective of this research is to utilize the finite element method to analyze the contact stress between a diabetic plantar and the orthosis used in treating ulcers. It is desirable to understand the stress distributions between the plantar and the ordinary insole or the total contact insole made of three different insole materials. In this research, finite element models of the foot in contact with an ordinary insole and with a custom total contact insole were built and a commercial finite element analysis package - MARC was used to investigate the contact pressure distributions at the plantar. Deformable contact bodies were used to simulate the contact behavior between the foot and the orthosis. Five different loading stages in the mid-stance phase were considered and the pressure distributions in the foot-regular insole interface and the foot-total contact insole interface were compared. Results showed that peak stress reduction of 57.78%, 53.57%, 83.70%, 85.79%, and 84.82% were found in each of the loading phases. The results from this research can provide valuable information for orthosis designers and makers for diabetic patients.
