| 5. | 4 . the influence of interfacial micro - crack point of new and old concrete on in adhesive fracture toughness is discussed 从界面断裂力学的基本理论出发,讨论了新老混凝土粘结面裂缝尖端微裂缝区对粘结面断裂性能的影响。 |
| 6. | The result showed that the failure of the steel die was mainly attributed to the generation of a large amount of meshy cracks on chromium plating surface 结果表明,镀铬层表面存在网状裂纹是导致模具表面出现微裂缝的主要原因。 |
| 7. | Dissolition is favorable for secondary porosity , thus forming available reservoirs in some sections of low porous and low permeable clastic rocks 从而使某些砂岩段在低孔低渗储层中形成较发育的次生溶蚀孔隙和成岩微裂缝,并成为有效孔隙。 |
| 8. | The conductive coat has been applied on concrete test blocks during the compression test , the data shows that the conductive coat is rather sensitive to formation and extension of tiny cracks 将导电涂膜应用于混凝土试块的抗压试验,结果发现导电涂膜在快速加、卸载条件下对混凝土微裂缝的出现及扩展相当敏感。 |
| 9. | The simulation result of performance of concrete was compared with that of the experiments . furthermore , the three - dimensional random aggregate model was established and the three - dimensional mesh of simple supported beam was generated automatically 混凝土的破坏,实际上是由于其内部的微裂缝的萌生、扩展、相互汇合,进而形成宏观裂缝贯穿混凝土而导致其失稳破坏的过程。 |
| 10. | But thermal stress ca n ' t be calculated without damage . and then it provided in this article the equation of the elementary damage , material intensity , elasticity modulus and temperature evolvement of rupture energy . 6 微裂缝的形成与发展仍然是由温度应力造成的,但此温度应力应是考虑损伤行为的应力,据此,文中导出了反映初始损伤、材料强度、弹性模量以及断裂能的温度损伤演变方程。 |
