摘要
摘要采用有限元软件SIMULIA对金属骨板进行疲劳寿命预测。研究了两种常用的外科植入物材料:用于植入物的1.4441 (ASTM F138)不锈钢和Ti6Al4V ELI (ASTM F136)钛合金。通过实验研究确定了两种材料的材料参数。为了将预测结果与实验实测数据进行比较，对两代骨板进行了四点弯曲疲劳试验。
The Mechanical Properties and Fatigue Prediction of a New Generation of Osteosynthesis Devices
Abstract The aim of the study was to predict the fatigue life of metallic bone plates employing SIMULIA fe-safe software. Two materials commonly used for surgical implants were subjected to investigation: 1.4441 (ASTM F138) stainless steel for implants and Ti6Al4V ELI (ASTM F136) titanium alloy. The material parameters of the two materials were determined from experimental research. Four-point bending fatigue testing was conducted on two generations of bone plates in order to allow for the comparison of the prediction results with the measured data from the experiments.
