摘要 目的研究三翼臼髋关节假体植入后在静载荷作用下骨盆结合处周围的变形状态。方法用数字图像相关方法对施加载荷前后的骨盆上感兴趣区域的数字图像进行了计算。结果显示了与三翼臼假体结合处的骨盆外侧面应变分布呈现非均匀的复杂应变状态,且随着载荷的增加最大应变分布区相应扩展。结论数字图像相关方法是一种较有潜力的非接触全场测量方法,有望在生物力学中得到更多应用。 Obejective To quantitatively research the deformation distribution of the outside pelvis around the replaced artificial acetabulum joint under static loads. Methods Digital image correlation is used to measure full-field surface deformation of test part. Results The deformation state is nonhomogenous and complicated. Conculsion Digital image correlation is a prospective non-contact full field optical technique to be used in biology mechanics.
