Five main phenomena were found, firstly, the high plasticity clay could well suitable to large deformation, and had strain-hardening behavior obviously, as well as, the little dilatancy; secondly, there was no correlation between stress paths and shear strength but the stress-strain relations were influenced by stress paths; thirdly, the little stress increment ratio, the higher increase speeding of shear stress and breaking strength under the condition of same initial normal stress; the fourth, the relations between normal strain and normal stress in simple shear test was consistent with which in the single-direction compression test, if there was no dilatancy; the last, the curve of relation between stress ratio and shear strain could be well simulated by hyperbola.
试验结果表明,高塑性粘土能够较好地适应大变形,接触面剪应力与切向应变关系呈剪切硬化型曲线,法向剪胀不明显;接触面剪切强度与应力路径无关,应力应变关系与应力路径密切相关;初始法向应力一定,应力增量比越小,剪应力增长越快,对应的破坏剪应力也越高;无剪胀发生情况下,法向应变与法向应力关系曲线与单向压缩试验具有一致性;应力比与切向应变呈良好的双曲线关系。

Five main stalk crops planted in northern China including wheat, corn, broomcorn, soybean, and millet, were chosen to be the samples of the experiments. About seven morphological traits (such as plant height, ear length, ear weight, moisture content and so on) were measured in the crop mature period. The maximum shear force during shearing process, through static test equipment, at the second internode of the basal stalk, was recorded. And shear strength of each crop was calculated to find the differences of shear strength among different crops. The optimal regression models of shear force and morphological traits were obtained by multiple linear regression method with Statistics Analysis System. The equation based on the regression models was constructed.

The main reason why quarter-sawn board of Larch had greater dry compressing shear strength than flat-sawn board of Larch in normal conditions was great difference between springwood and summerwood of Larch.
造成桦木径切板胶合强度试件的常态压缩剪切强度比弦切板的小的主要原因是由于桦木木材本身弦径向强度的差异,即桦木径向的顺纹抗剪强度比弦向的大。

Because the strength of springwood was very low, the strength of board which included more springwood was low. The main reason why there was no difference in wet compressing shear strength between quarter-sawn board and flat-sawn board was that quarter-sawn board had a lot of pits on radial cell wall and in flat-sawn board xylary rays were transversely cut and left a lot of pores which provided a kind of tunnels for water.
造成柞木径切板的反复煮沸压缩剪切强度与弦切板的反复煮沸压缩剪切强度没有显著性差别的主要原因是柞木细胞壁径面上的纹孔很多,而弦面上的木射线在经刨削后是横断的,留下许多孔隙,这使得弦径向均有成为水分通道的孔隙,造成柞木径切板的反复煮沸压缩剪切强度与弦切板没有显著性差别。

The main reason why quarter-sawn board of Birch had smaller dry compressing shear strength than flat-sawn board of Birch in normal conditions was that Birch had different shear strength to the grain between quarter-sawn board and flat-sawn board. Meanwhile xylary rays in flat-sawn board were transversely cut and left a lot of pores in the flat-sawn board, so adhesive can enter these pores and turn into adhesive nail. While these pores provided a kind of tunnel for water, so cause this phenomenon that wet compressing shear strength of flat-sawn board of Birch was smaller than that of quarter-sawn board of Birch. The possible reason why quarter-sawn board of Oak had greater dry compressing shear strength than flat-sawn board of Oak in normal conditions was that ratio of springwood on quarter-sawn board and flat-sawn board was different.
造成柞木径切板的常态压缩剪切强度比弦切板的常态压缩剪切强度大的主要原因是,在径切板和弦切板上早材胶接的比例不同,径切板的胶合强度试件上早材胶接的比例相对少,而弦切板的胶合强度试件上早材胶接的比例比径切板的胶合强度试件上早材胶接的比例相对大,由于早晚材胶接过程中强度决定于早材,这部分胶接强度比较低,这就使得柞木径切板的常态压缩剪切强度比弦切板的大;同时在柞木弦径面胶接过程中由于实际胶接面积的不同也能造成弦径面上API胶粘剂与之形成的化学键的数量不同,这也是造成柞木径切板的常态压缩剪切强度比弦切板的大的原因之一。

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.
