It was also found the main direction of permeability rotated after shearing and the permeability decreased with the increasing of shearing angle . the excellent prediction of shearing permeability by the lai - young model provided theoretical support for the numerical filling simulations in complex parts 实验研究了剪切变形对纤维织物渗透率的影响,发现剪切变形后主渗透率方向发生旋转,主渗透率值随剪切角增加而降低。
A program , which can be used to analyze the self - vibration frequency of box girder bridges , is compiled using fortran language . the beam element and solid element are included . also the effect of shear deformation on self - vibration can be calculated too using the program 在研究时,用fortran语言分别编写了按二维梁单元和三维块体单元进行桥梁结构自振特性分析的程序,在按二维梁单元进行编程时,考虑了梁剪切变形的影响。
In this paper , the theory for lateral vibration of pile foundation with consideration of shear deformation of pile is established , and the influence of the ratio of pile length to its diameter , the ratio of pile stiffness to soil stiffness and dimensionless frequency were studied systemically 本文建立了一整套考虑桩体剪切变形的桩基水平振动分析理论,并较系统地研究了桩的长径比、桩土刚度比、激振频率等因素对桩基水平动力响应的影响。
When targets penetrated by flat - ended projectile , shear deformation along the penetration direction appears , at the same time compressive deformation also appears in the material that is in front of the projectile . the compressive deformation begins at the back surface of the target and spreads inward 钝头弹侵彻下,侧壁材料发生轴向剪切变形,同时,弹体前方的材料发生压缩变形,压缩变形首先在靶板背表面开始,而后自背表面向靶内传播。
Accordingly , solution for the dynamic response of grouped piles taking consideration of shear deformation was developed by using superposition principle , and the effects of shear deformation and the other factors on the horizontal displacement and the distribution of shear forces at pile head were investigated 在此基础上,利用叠加原理得到了考虑桩体剪切变形的群桩水平动力响应解,并分析了剪切变形和其他因素对桩顶水平位移以及桩顶剪力分布的影响。
With the increasing of raft foundation thickness , the hypothesis of kirchhoff will be invalid due to the incapable neglecting of transverse shearing deformation . the correct solution can not be deduced through theory of thin plate any more since the influence of transverse shearing deformation does not take into account 随着板厚度的增加,横向剪切变形不可忽略, kirchhoff假设不再成立,薄板理论已不能给出正确的解答,横向剪切变形的影响必须加以考虑。
