Ligament primarily stabilizes the diarthrodial joints and function to provide
stability and support during the motion of diarthrodial joints. These functions are
assisted by the congruent geometry of the articulating joint surfaces and
musculotendinous forces. Ligament exhibits viscoelastic, or time-dependent
behavior, like many tissues in the body. From the medical point of view an
understanding of the biomechanics of ligaments are crucial for the understanding
of injury mechanisms and to evaluate existing surgical repair techniques. The mode
of failure in ligaments depends strongly on the rate of loading. Thus, ligament
viscoelasticity is an important determinant of tissue response to loading, and
viscous dissipation by the tissue modulates the potential for injury. Many
mathematical models have been developed to describe the complexity of these
behaviors that could include the microphysical interactions of various constituents
but none of them seems to represents the overall properties of these structures.
Models can be an important tool in understanding tissue structure-function
relationships and elucidating the effects of injury, healing, and treatment. The main
objective of this work is to study from the biomechanical point of view, the
behaviour of an example of the medial collateral ligament in response to stress and
strain effects to evaluate the biological behaviour of the ligament. The strain effect
as example of the modified superposition method and analyze the results and the
model that can express the medial collateral ligament behaviour
