The Shear Modulus and Structure of Cartilage Tissue
Keywords:cartilage tissue, shear modulus, deformation, network model
Cartilage tissue has been considered as a polymeric gel network formed from chains of fibrillar proteins and proteoglycans. A theoretical model of the network consisting of network units connected by inter-unit chains is proposed, the corresponding deformation mechanism for cartilage tissue is developed, and a formula for the shear modulus is obtained. The shear modulus for elastic cartilage tissue is also determined experimentally. The number of inter-unit chains in the model of the elastic cartilage tissue is evaluated to be equal to 10.
