Mechanical response and failure processes of anterior cruciate ligament from static to dynamic loading rates

摘要

In daily life activities, knee joint ligaments and in particular the anterior cruciate ligament (ACL) are commonly injured and the knowledge of their mechanical properties is therefore necessary to design artificial materials. In most cases, rupture occurs at the bone-ligament interface, under dynamic loading (Subit et al. 2008), but the failure process depends on the elongation rate.This paper presents experimental results obtained using rabbit femur-ACL-tibia complexes (FATCs) submitted to a wide range of loading rates and analysed using digital image correlation (DIC).
