| 5. | Fracture energy and crack length , as two imperative parameters of aggregates , can ' t be measured by usual methods 摘要断裂能和断裂区长度作为骨料的重要参数无法通过常规方法进行检测。 |
| 6. | The fracture energy gf of concrete is one basic material characteristic , representing the energy necessary to create a unit area of fracture surface 混凝土断裂能g _ f是材料的一个基本性能,表示扩展单位裂缝面所需要的能量。 |
| 7. | In this thesis , the modified critical fracture resistance was defined by excluding the viscoelastic dissipation , which is related to the intrinsic fracture energy 本文利用内禀断裂能的概念,定义了不含粘性耗散项的临界断裂阻力。 |
| 8. | Whereas gf , although an energy index , only denotes the average energy absorbed during the whole concrete fracture process , ignoring those two procedures mentioned above 作为一种能量指标的混凝土断裂能g _ f只能表征混凝土断裂全过程的平均能量吸收,而并不涉及这两个阶段的能量变化。 |
| 9. | 3 . different test methods in determining those three fracture energy parameters arise one problem , that is whether gf . gfs and gfu are consistent as obtained from different measuring methods 由于测试混凝土三个断裂能参数采用的方法不同从而带来了一个问题,即不同的测试方法所得到的g _ f 、 g _ ( fs )和g _ ( fu )是否一致 |
