Experimental Study of Variation between Quasi-static and Dynamic Load Deformation Properties of Bovine Medial Collateral Ligaments 2009-01-0392

In a significant number of automobile crashes involving pedestrians, the ligaments which control the stability of the knee, often get severely loaded. In lateral impact on knee during automotive crashes, varus-valgus motion results in failure of ligament by avulsion or by rupture in the middle region It is known that properties vary in different regions of the ligament. Experimental measurement of tensile load-elongation behavior of the middle region of bovine medial collateral ligament at strain rates of 10−4 /s to 160/s are reported here. The results show that the stress-strain behavior is linear under quasi-static loading whereas it is nonlinear and strain rate sensitive in dynamic loading conditions.
