| 摘 要： | 利用蠕变本构方程和材料力学中的小变形假定导出了三点弯曲下的蠕变关系式，利用两种堇青石－莫来石材料的试验初步拟合上述关系。研究表明：稳态蠕变时，中点挠度的速率与应力呈指数关系。

| Abstract: | A creep equation for three points bending was deduced by means of axial creep constitutive equation and small deformation hypothesis in mechanics of material. Two kinds of cordierite-mullite material were tested and the result was in accordance with the creep equation. The research reveals that there is a linear logarithmic correlation between maximum deflection velocity and stress in the stable state of creep. |
