| 7. | The longitudinal stresses in the tunnel structure calculated by using the model of tamura & okamoto are obviously greater than the stresses in transverse direction obtained by using two dimensional finite element analysis . it is proposed that the axial and bending stresses should not be ignored for the underground structural design 计算结果表明,由弹簧质量模型算得的地下结构在地震作用下纵向振动和横向振动产生的纵向和弯曲正应力及剪应力明显高于由二维平面有限元算得的横向平面内产生的正应力和剪应力,由此可见轴向应力和弯曲应力是地下结构抗震设计中不容忽视的因素。 |
| 8. | Zircaloy - 4 sheet , which was cold - worked followed by recrystallization annealing , exhibits longer lcf life in the rolling direction than that in the transverse direction , and the fact that difference in lcf life between both directions becomes larger as the range of plastic strain becomes lower can be attributed to the texture effect , p - solution treatment deteriorates the alloy ' s lcf property because the treatment lowers the average value of alloy ' s schmid factors , and the subsequent annealing - treatment in a - phase range has a impact on the lcf properties , i . e . the subsequent annealing - treatment at 500 ? for 1 . 5h results in better property than that at 750 for 1 . 5h , which comes mainly from the fact that the alloy annealled at 500 for 1 . 5h has lower amount of the precipitate particles than the alloy annealled at 750 for 1 . 5h 对于冷加工后经再结晶退火处理的zr - 4合金,轧制方向的低周疲劳寿命比横向要大。随着_ p的降低,两个方向的低周疲劳寿命的差别相应增加,这是由于合金中存在织构的缘故。冷加工后经再结晶退火处理的zr - 4合金在固溶处理后,抗疲劳性能明显降低,这主要是由于固溶处理降低了合金的schmid因子;固溶处理后在相区的退火对疲劳性能有影响,即500 1 . 5h退火的抗疲劳性能要优于750 1 . 5h退火,这主要与500 1 . 5h退火的合金中沉淀相粒子的数量较少有关。 |
