The effects of thickness on biomechanical behavior of articular cartilage: a finite element analysis

It is important to study joint contact mechanics in order to understand the human joint function and degeneration. In previous studies, the cartilage behavior was investigated using computational method assuming the cartilage to be flat and an ideal thickness. But, this assumption may not appropriat...

The effects of thickness on biomechanical behavior of articular cartilage: a finite element analysis
description It is important to study joint contact mechanics in order to understand the human joint function and degeneration.
