| 6. | Spray deposited porous aluminum alloy sheets easily have surface and edge crack when they are directly rolled due to the porosity and metallurgical bond 摘要喷射沉积多孔铝合金板坯由于有孔洞且缺乏良好的冶金结合,直接轧制时易出现板坯表面裂纹及边裂。 |
| 7. | From the hypothesis of linear viscoelasticity , we predicted the time of life of the three specimens with edge crack which fractured in out experiment at last in view of energy releasing . however , we found that the predicted values were on the low side obviously , so we analyzed the reason of being non - linear . on this basis , we modified the method 本文的第四章从线粘弹性假设出发,从能量释放率的角度对实验中最终断裂的三今含边裂纹的试件的寿命进行了预测,并与实验结果进行了对比,发现预测值明显偏低,分析了产生非线性的原因,进行了非线性修正。 |
| 8. | By using moire method , three groups of pmma specimens with single edge crack were experimentally researched under constant stress , especially the strain field around crack - tip . through measure and analysis , we could see its time dependence clearly . we compared the actual strain distribution with the theoretical linear viscoelastic strain distribution 利用云纹法,对四组含边裂纹的pmma试件在恒应力条件下的裂尖周围的应变场进行了测定、分析,可以看出其明显的时间相关性,并与基于线弹性假设的裂尖应变场进行了对比。 |
