Development and validation of lumbar spine finite element model

Abstract: The functional biomechanics of the lumbar spine have been better understood by finite element method (FEM) simulations. However, there are still areas where the behavior of soft tissues can be better modeled or described in a different way. The purpose of this research is to develop and validate a lumbar spine section intended for biomechanical research. A FE model of the 50th percentile adult male (AM) Total Human Model for Safety (THUMS) v6.1 was used to implement the modifications. The main modifications we… Show more

“…Previous research has explored various mathematical models that describe the stress-stretch behavior of bone, each catering to different aspects of bone mechanics and applicable to a range of scenarios from everyday activities to traumatic impacts. Depending on the error tolerance of the model considered, it can be useful to differentiate between linear and nonlinear mathematical models of mechanical stress-strain (or stretch for large deformation) of bone, including isotropic or orthotropic elastic, elastic-plastic, viscoelastic, and poroelastic models [1][2][3][4][5][6][7][8].…”
