This paper is important, because the literature does not treat this topic deeply, and the mechanical properties in elbow joint, considering the thickness of hyaline cartilage of the elbow are neglected, due to its low thickness. The paper proposes a study based on a theoretical platform. Firstly, it approached the study of elbow joint films (cartilage), because a nonlinear study would involve a multitude of internal and external factors that are supposed to keep out, and theoretical research would be particularly cumbersome, if not impossible. In addition, firstly (case1) this study, be it linear, has not been approached by the literature and it is particularly important to know the mechanical behaviour of the joint of the cartilage. It played with the ultimate goal of determining the linear mechanical properties perspective, elongation and resistance to hyaline cartilage from breaking it, regarding the elbow joint. In the case 2 of study, it be analysed the nonlinear evolution, regarding stress and strain properties base on the anterior tissue experiments (not hyaline cartilages), given by specialty literature. Theoretical approach to this
problem, from the standpoint of mathematical models developed, they try to observe as accurately model real hand-arm system, it was shown that the mechanical properties (stress and strain) of the articulation the elbow are not neglected.
Key words: cartilage, elbow joint, mechanical characteristics, stress and strain.
