  elastic correction
In practice, the 2-dimensional elastic correction exceeds the opposite hydrodynamic correction found previously, and so the predicted flow resistance is greater in the transonic than in the sonic configuration, as observed.
      
Figure 4 summarizes the effects of the triaxiality of load ing and of the nonlinear elastic correction.
      
The magnitude of elastic correction may be a good indication of the corresponding surface strain of the nanocrystalline grains.
      


Based on the equation used to estimate the shear fracture energy in slipweakening model, the method of displacement measurement in triaxial test is analysed. Displacement measured across the rock fracture by using a transducer mounted directly on the rock specimen is compared with piston displacement measured outside the pressurized vessel. We show that the former method is more precise and reliable than the latter. As the sampling rate is much faster compared with the stick slip process, the relation between...

Based on the equation used to estimate the shear fracture energy in slipweakening model, the method of displacement measurement in triaxial test is analysed. Displacement measured across the rock fracture by using a transducer mounted directly on the rock specimen is compared with piston displacement measured outside the pressurized vessel. We show that the former method is more precise and reliable than the latter. As the sampling rate is much faster compared with the stick slip process, the relation between stress and displacement can be obtained directly. Both internal and external transducers are used at same time to measure the same stick slip event. There are important differences between the results from these two types of tranc-ducers. The shear fracture energy (G) estimated by the former is much higher, from three to ten times, than the latter, and therefore is much closer to the seismologically inferred values. The reason of the lower value obtained by the external fransducer is also briefly discussed.

从滑动弱化模型剪切破裂能G的计算公式出发,对三轴实验中常用位移测量方法作简要分析,认为改用弹簧应变片式位移计直接测量断层位移比用位移传感器在容器外部测量更能真实地反映粘滑的动态过程.作如此技术上的改进以后,当频率响应和采样速率比粘滑动态过程高得多时,就能直接得到τ(Δu)积分曲线而无需进行弹性修正.对同一粘滑事件,分别用弹簧应变片式位移计和位移传感器在高压容器的内外同时进行位移测量,在各种条件下,前者得出的G值总比后者高得多,约为3—10倍.初步的分析表明,后者偏低的主要原因在于容器外的位移计不能及时地反映粘滑时的位移变化,而新的方法在一定程度上克服了这一缺点,因而更接近于用地震学方法所得到的G值.

Based on Barker's short-rod-specimen method, the concept of viscoelastic correction coefficient is proposed. This coefficient makes it possible that Barker's method, an elastic-plastic method for measuring fracture toughness, can be used to obtain K_(Ic) of polymer materials which have a considerable viscoelastic response. When the correction coefficient equals 1, it is again the ideal elastic-plastic case.

本文在Barker的短圆柱试件法基础上,提出了一个粘弹性修正系数的概念,使这个实验测定断裂韧性的弹塑性方法能够用于测量粘弹性响应较大的高分子材料的K_IO值,而当修正系数为1时,又回到理想的弹塑性情况。

he main purpose of this paper is to introduce some efforts of the“Analvtical investi- gation of the aircraft flight loads”,which was one of the research tasks of the aircraft strength specification in the period of the seventh-five year program. Analytical results shown in this pa- per include:flight envelopes,manuvering histories,static elastic correction,aerodynamic loads and inertial loads,loading balance of the aircraft,bending moments,torsion moments and shear- ing loads at specified cross sections of the airframe. All these results were studied and compared with the original design loads conditions of the fighter aircraft. In addition,some points of view about further investigation and implementation of the“NATIONAL MILITARY SPECIFICA- TION OF TNE STRENGTH AND LOADS”are presented.
