A viscoelastic model of the shear response of the Rhesus monkey intervertebral disk, represented by a series chain of four Kelvin units is presented. Two types of investigations are carried out to assess the validity of the model: 1) determination of material properties by comparison with experimental strain creep behavior of the disk; and 2) validation of this viscoelastic model by accurately predicting the experimental results of stress relaxation tests. The use of the series Kelvin units approach provides the first analytical mechanical model capable of predicting the creep and relaxation functions for the intervertebral disk in shear.
提出了一种以四个开尔文单元的串联链表示的恒河猴椎间盘剪切响应的粘弹性模型。进行了两种类型的研究来评估该模型的有效性：1）通过与椎间盘的实验应变蠕变行为进行比较来确定材料特性；2）通过准确预测应力松弛试验的实验结果来验证该粘弹性模型。串联开尔文单元方法的使用提供了第一个能够预测椎间盘剪切蠕变和松弛函数的解析力学模型。
