Pediatric age did not have a statistically significant effect on the average linear stiffness.
儿童年龄对平均线性刚度无显著性影响。
2
The model to predict stiffness was then established based on the stiffness volume average method. The elasticity constants of the material were obtained.
基于刚度体平均方法，建立了相应的刚度预报模型，得到了三维四向编织复合材料的工程弹性常数。
