| 摘要: |
| 在描述苹果蠕变现象四元件Burgers模型的基础上，建立了四元件五参数模型，研究了静载损伤与所受载荷、作用时间、变形量之间的关系，提出了苹果蠕变损伤的主要原因是其变形量超出了临界变形值，并且模型的粘弹性系数与损伤体积有着显著的线性相关关系。 |

| A Study on Creep Properties and Static Loading Damage Mechanisms of Apple |
|
|
| Abstract: |
| The four elements-five parametres model was established to describe the
creep phenomena of apple based on the four elements Burgers model. Relationships of
static damage and loading, as well as time and deformation were investigated.The reason
of creep damage was deformation values in excess of threshhold.There existed a remarkable linear correlation between the models viscoelastic coefficients and bruise volume. |
| Key words: apple,creep,static loading,damage |
