| 摘 要： | 用软组织拉伸力学方法对８个８－１５岁新鲜尸体颞下颌关节外侧壁试件共３１个进行纵向应力松驰和拉伸破坏实验。结果表明：关节外侧壁是囊和韧带结构的复合体，抗拉伸和抗变形能力较弱，应力松驰方式在缓冲外力载荷可可能起主要作用。

| Abstract: | Tensile mechanical experiments were made on 31 lateral capsular ligament complex spencimens from 8 fresh temporomandibular joints of human cadavers aged 8~15 years. The tests included stress relaxation at different strain rates and tension test at constant strain rate. Some biomechanical material properties of the tissue were determined. The result showed that the complex had lower tensile strength and tensile stiffness, and the stress relaxatioin was the most important mechanism of spreading stress and absorbing shock. The stress relaxation function and the constitutive equation of stress and strain were obtained with Fung's Quasi Linear Viscoelastic Theory fitting the experimental results. |
