| 1. | Have you ever felt like you are at your breaking point 是否有过已经处在强度极限的感觉? |
| 2. | Relations between the fractal dimensions of tensile fractures and the tensile ultimate stresses for the grain composite material caco3 abs 拉伸断口表面分形维数与其拉伸强度极限的关系 |
| 3. | The fatigue tests of the composite materials under the constant amplitude and two double - level stresses are investigated experimentally 进行了应力为65强度极限的常幅应力以及两种双级应力的疲劳试验验证。 |
| 4. | After pretension 0 . 1 strain and pretorsion to 14 , whereas the strength limit keep on increasing in company with the pretorsional capacity 其中屈服极限在预拉伸应变0 . 1后再预扭转14后达到最大值,而强度极限随着预扭转量的提高不断增大。 |
| 5. | Therefore , this design makes material sufficiently used , the weight of road wheel effectively lightened . at the same time , stress distribution is more reasonable 结果表明:最大应力值接近铝合金车轮的强度极限,充分利用了材料,有效的减轻了重量,应力分布更加合理。 |
| 6. | The result shows the maximal stress value in original design is much less than the breaking point of aluminum alloy , which make material wasted . so it is necessary to optimize structure of road wheel 结果表明:最大应力值远小于铝合金车轮的强度极限,强度储备很大,造成了材料的浪费,存在着进一步优化的必要。 |
| 7. | To explain the inverse hall - petch relation in nanocrystalline metals , a geometric model is made , which assumes that the grains are spherical crystals , and the thick of grain boundary is considerable compared with the microcrystalline metals 提出了一个球形晶体纯晶界滑移几何模型,得到出现反hall - petch关系的条件和小晶粒尺寸条件纳米晶金属材料的强度极限。 |
| 8. | The stress of slag rests with the structure , physical characteristic , and heat transfer status of slag . taking no . 1 boiler of beilun thermal power plant as example , the walltube thermal stress and the destroying impact on slag are researched 得出锅炉大范围变负荷运行时热应力能够超过渣的强度极限引起渣结构破坏的结论,渣层的热应力主要取决于渣的结构、物理特性和传热状态。 |
| 9. | Abstract : by the using of the theory of plastic mechanics , a calculated formula of ultimate strength of shearing stress is obtained for metallic materials with torsion of circular shaft , and the experimental results about low - carbon steel are given 文摘:利用塑性力学基本理论,建立了具有塑性屈服及强化特性金属材料圆轴扭转的剪应力强度极限的计算公式,并给出了低碳钢剪应力强度极限的处理结果 |
| 10. | The consequence is , when the majority of structure does n ' t enter yield habitus , but the position of belly - board has been reached the ultimate habitus , it lead to material waste of the other positions , we should pay attention to the disastrous result it will bright to us 它带来的后果就是当结构的大部分处于弹性状态时,箱梁腹板处由于剪力滞效应一般最先达到强度极限状态,导致腹板间材料的抗力没有得到充分的使用,如不引起重视会带来灾难性后果。 |
