Abstract
Objective The present biomechanics researches of costal cartilage are not enough and mainly limited to plain experimental analysis. This paper focuses on the function relationship for the viscoelasticity of costal cartilage. Methods We established the stress-strain function and a normalized stress relaxation function and the relaxation function by least-square method. In addition, a generalized Kelvin model for viscoelastic materials was built to express the normalized creep function, and the simulation analysis on fitting accuracy of the functions was carried out. Results The functions and model built in this paper could represent the biomechanics of costal cartilage well. Conclusions This research can be utilized as reference for the finite element analysis of three-dimensional visualization model of costal cartilage and further research on normal physiology and damage mechanism of costal cartilage.关键词
