Abstract. The effects of consecutive and gradually increasing strain on the mechanical behavior of rat medial collateral ligaments (MCLs) were studied to characterize and understand the damage evolution process. Displacement-controlled tensile tests were conducted on femur-MCL-tibia complexes (FMTCs) harvested from Sprague Dawley rats. Each FMTC was loaded to a given displacement, unloaded, and re-loaded to another increasing displacement several times until complete failure occurred. Two different phenomena were observed which indicated the initiation and propagation of damage: the elongation of the toe region and decrease in modulus of the linear region.
