Abstract：
:In this work we propose a method to estimate the elastic properties of the extracellular matrix of articular cartilage, once the elastic properties of the chondrocytes and the whole tissue are known. The influence of the elastic properties of the tissue and the cell concentration on the estimated elastic properties of the matrix are investigated.

杂志文章abstract：:Uncrimping of collagen fibers in the arterial wall is an integral process in regulating the macro-level mechanical response of arteries. Uncrimping of collagen fibers leads to a gradual, but significant strain-stiffening response of the artery at physiological pressures and prevents overdistention at elevated pressure...
