Shows resistance to compression, durability and high tensile strength. The reason that intervertebral discs exhibit a large amount of tensile strength, which allows them to absorb shock, is because they possess _____. We hypothesized that under such compressive loading conditions matrix damage, as evidenced by a reduction in tensile strength of cartilage, would precede visible surface fibrillation. Stresses used in this study are comparable to a previous cyclic compressive study of cartilage-on-bone specimens , which reported that the mean fracture strength of bovine articular cartilage was 35.7 MPa. The 20 tracheal cartilage samples were subjected to one-dimensional tensile test with Shimadzu electronic universal testing machine Japan, at the tensile test speed of 5 mm/min. bone. This layer-wise variation in tensile stiffness reflected the orientation of the collagen fibrils in the tissue. Although pyridinoline has been shown to correlate with tensile strength and stiffness in bovine articular cartilage , this is the first study to show that pyridinoline also contributes to the mechanical properties of other joint tissues. while it sustains compressional loading; Biomechanics of Cartilage Sunil MPT – 1 SEM 2. Cartilage ECM is composed mainly of two components defining its mechano-physical properties: the collagenous network, responsible for the tensile strength of the cartilage matrix, and the proteoglycans (mainly aggrecan), responsible for the osmotic swelling and the elastic properties of the cartilage tissue. It has relatively high compressive strength, of about 170 MPa (1800 kgf/cm²) but poor tensile strength of 104–121 MPa and very low shear stress strength (51.6 MPa), meaning it resists pushing forces well, but not pulling or torsional forces. OBJECTIVES To determine the biomechanical characteristics of septal cartilage (SC) and costal cartilage (CC) taken from fresh cadavers using tensile testing and to establish CC graft material of a suitable thickness (ie, with tensile characteristics closest to those of SC). The relationship between the tensile properties of articular cartilage and age has been investigated in vitro in the human knee joint. What tissue has lacunae, calcium salts, and blood vessels? Among 95 cartilage pieces from 12 human cadavers (mean [SD] age, 67.7 [12.6] years) and 240 constructed L-strut models, L-strut thickness was the only factor correlated with nasal septal cartilage yield strength (coefficient for thickness, 5.54; 95% CI, 4.08-7.00; P < .001), with an adjusted R 2 correlation coefficient of 0.37. It is similar to extracellular matrix components. fibers are not normally visible. To understand there relevance of this figure, aluminum has a tensile strength of 70 megapascals and nylon has a tensile strength of 80 megapascals [29]. On the other hand, the tensile strength of cartilage and shear strength of subchondral bone were 3.75 +/- 0.75 MPa (n = 17) and 2.45 +/- 0.85 MPa (n = 15) respectively. Hydrogel is a polymer matrix containing a large amount of water. However, hyaline cartilage is considered the weakest of the three cartilage types. II. collagen fibers. The tensile stiffness of the tracheal cartilage fell in the range 1-20 MPa and was found to decrease with increasing depth from the outer surface of the tissue. It can be applied to bone and cartilage tissues. Collagen II forms fibrils that provide tensile strength throughout the extracellular matrix. METHODS Grafts of varying thickness were harvested from the central part of the seventh-rib CC and SC of 18 fresh cadavers.
