Evaluation of the use of the Yeoh and Mooney-Rivlin functions as strain energy density functions for the ground substance material of the annulus fibrosus

Due to the importance of the intervertebral disc in the mechanical behavior of the human spine, special attention has been paid to it during the development of finite element models of the human spine. The mechanical behavior of the intervertebral disc is nonlinear, heterogeneous, and anisotropic an...
