The Application of Contact Theory in Finite Element Model of Human L1-L5 Lumbar Segments
Appling the contact theory The finite element model of L1-L5 segment was established with self-compiled software and Hyper Mesh.Based on the spine CT continuous images of L1-L5 segments of the healthy volunteer,the three-dimensional finite elements model of L1-L5 vertebrae structure was constructed by the combination of self-compiled software and Hyper Mesh.endplates and joint cartilage intervertebral disc and ligament structure were also simulated.Between the high and low articular processes adopts the surface-surface contact theory to carry on processing.The three-dimensional finite element model was built structure integrity,with good geometric similarity.The results of the finite element model were matched to the results of the vitro experiment of biomechanics.The use of self-compiled software and Hyper Mesh can improve the finite element model of lumbar motion segment building speed and accuracy,the introduction of contact theory finite element model can improve the reliability and auteenticity.
