Dynamic stress-strains relations of sheet at lower and middle strain rates(ε=10~(-5)-10~(-1)-S(-1))have been experimentally measured on the material test machine DSS-25 by tension, which gives the loading speed with a controllable value, and can be made constant during a tension process. In order to obtain the information of deformational resistance at higher strain rates, a new high pressure azotic expansion test machine has been constructed which makes it possible to obtain strain rates,ε=lO(-l)-10~2 s(-l),...

Dynamic stress-strains relations of sheet at lower and middle strain rates(ε=10~(-5)-10~(-1)-S(-1))have been experimentally measured on the material test machine DSS-25 by tension, which gives the loading speed with a controllable value, and can be made constant during a tension process. In order to obtain the information of deformational resistance at higher strain rates, a new high pressure azotic expansion test machine has been constructed which makes it possible to obtain strain rates,ε=lO(-l)-10~2 s(-l), even higher, and to measure stress-time and strain-time relation.

在DSS-25试验机上,用拉伸板状试件的方法,进行了中、低速(10~(-5)~10~(-1)s~(-1))的试验.该试验机在全部拉伸过程中可保持其加载速度恒定.为了获得更高的应变速度,组装了氮气膨胀式拉伸仪,它的速度可达10~(-1)~10~2s~(-1),并且可以给出应力-时间和应变-时间关系曲线.含铜软钢的试验表明,应变速度对变形抗力有明显的影响.在试验条件下,随着加载速度的增加,变形抗力有显著的提高.根据金属位错的理论,确定了变形抗力的理论结构模型,它包括应变速度ε,变形程度ε对变形抗力的影响和A、B、n_1、n_2等系数.?从试验结果来看,在很宽的变形速度的范围内,该公式较好的反映了实际情况.

In order to investigate the effect of low temperatures on the fracture behaviour of ultra high-strength steels, surface-cracked plate specimens of 37SiMnCrMoV steel (oil quenched and tempered at 280℃)were adopted.Fracture tests were arranged within the range of temperatures from -196℃ to 20℃.With variation of the temperature. The fracture toughness values varied frcm 85 kgf/mm~(3/2) (at-196℃)to 195.7kgf/mm~(3/2) (at 20℃),and the percentage of quasi-cleavage area below the crack in the central flat fracture surface...

In order to investigate the effect of low temperatures on the fracture behaviour of ultra high-strength steels, surface-cracked plate specimens of 37SiMnCrMoV steel (oil quenched and tempered at 280℃)were adopted.Fracture tests were arranged within the range of temperatures from -196℃ to 20℃.With variation of the temperature. The fracture toughness values varied frcm 85 kgf/mm~(3/2) (at-196℃)to 195.7kgf/mm~(3/2) (at 20℃),and the percentage of quasi-cleavage area below the crack in the central flat fracture surface varied from 100%(at-196℃)to 15%(at 20℃).The differences between the low-temperature brittleness behaviour of ultra highstrength steels and that of mild steels were compared and discussed.The influences of the holding time during austenization, the carbon content and the temper embrittlement on the fracture behaviour of ultra high-strength steels at low temperatures were investigated in this paper too.

In order to investigate the interaction between the two flanks of a seismic fault in the course of an earthquake, four groups of fracture experiments with different states of crack surfaces have been made. The experimental results showed that the states of crack surfaces have strong effects on the critical value of σc for specimens with crack of length 2a. The experimental results have been analized according to fracture mechanics.The following key techniques have been resolved in our experiments:1. A new method to produce pre-cracks in centre of the specimen has been used. Central penetrating cracks in plate specimens of glass, plexiglass and rock can be produced by means of three points bending which leads to local tension and crack initiation at one side of the specimen and penetrating the two sides.2. The strain gauges were placed at the crack tip areas, across which the crack are expected to grow, to monitor the crack initiation and to measure the corresponding strength σc of the experimental materials.

为了研究地震过程中断层面的相互作用,设计了四类裂纹面状况不同的断裂力学实验。实验结果表明,裂纹面的状况对于含裂纹材料的σ_c(2~(1/2))值有强烈的影响,并利用断裂力学的原理对结果进行了分析。 实验中解决了如下技术关键: 1.可用三点弯曲、局部受拉、单面启裂、双面贯穿的方法,在脆性材料板状试件(玻璃板、岩石板)以及有机玻璃板中预制中心穿透裂纹。 2.在裂纹端部预计裂纹扩展的区域内粘贴电阻应变片,用以判断并测量裂纹初始扩展及其相应的破坏应力σ_c的方法。
