Finite element analysis (FEA) is broadly used in engineering, it was initially applied to simulate and solve a variety of engineering mechanics, thermal, electromagnetics, and other physical problems. The principle is a collective to be composed by an infinite number of particles, and an unlimited number of degrees of freedom from the continuum approximation. Brekelmas and Ryblcki firstly applied the finite element method to orthopedic biomechanics research in 1972. The first cervical vertebra finite element model was established in 1982 by Hosey. With the computer and software technology advances in the past 20 years, finite element method in cervical spine biomechanics studies is increased and widespread.
有限元分析（FEA）在工程领域被广泛应用，它最初被用于模拟和解决各种工程力学、热学、电磁学及其他物理问题。其原理是将一个连续体近似为由无限多个质点组成且具有无限多个自由度的集合体。1972年，布雷克尔马斯和雷布利茨基首次将有限元方法应用于骨科生物力学研究。1982年，霍西建立了首个第一颈椎有限元模型。在过去20年里，随着计算机和软件技术的进步，有限元方法在颈椎生物力学研究中的应用日益增多且广泛。
