2.Author thinks that the direction of the maximum plastic distortion along a constant radius around the crack tip may be considered as the direction of shear - mode fracture ( named pmax - criterion ) and the load when located shear band prongs the ligament in the front of crack tip is regarded as the limited load of shear - mode fracture . ( 3 ) the fad ( fracture assessment diagram ) of titled crack is proposed based on achievements of mesomechanics about i - ii complex ductile fracture of metal , and the titled crack is classified two kinds : void - mode fracture is assessed by fracture assessment curve , and shear - mode fracture by limited load . ( 4 ) using a fe program based on plantle - ressue theory to calculate some mesomechanical parameters , a flange joint structure of a high pressure vessel ( design pressure 31 . 4mpa and the thickness of the hemispherical head is half of that of shell . ) is analyzed to determine whether the structure under operation pressure is safe or not , forecast the mode of potential invalidation and argue for the rationality of design of the structure
试件的整体断裂为剪切型,但在试件芯部裂尖钝化区中部出现了韧窝型启裂并有一定的扩展,说明局部较高的应力三轴度也会使韧窝型机制得以发展,但是不改变试件整体的剪切型断裂模式;对韧性断裂的剪切模式的细观机理做了一定的探讨,并且提出了含裂纹构件剪切型断裂的宏观判据:认为裂纹前方的集中剪切带中与裂纹尖端等半径处最大有效塑性应变出现的方向可以作为裂纹剪切断裂的方向(可简称为_ ( pmax )准则) ,集中剪切滑移带贯穿裂纹前方承载韧带时的载荷可以作为极限载荷;本文运用金属韧性断裂细观力学在一复合型韧性断裂方面的研究成果,采用失效评定图的形式,提出了倾斜裂纹的安全性评定方法的基本框架。
3.There are two contents in this paper : one is solve the control differential equation of box girder " s shear lag by dq method , the other is rules of the shear lag for single - box - multiple - cell box girders . first we introduce what is shear lag and the status of research ; we introduce dq method and use dq method to solve several bridges in the third chapter ; also we introduce the software - ansys and analysis several bridges by ansys in chapter iii ; in chapter iv we assume several bridge models and get the stress distribution under concentrated load and distributed load ; we summarize the paper in chapter v and propose the advancing direction of shear lag
文章首先介绍了剪力滞定义及目前研究情况;第三章介绍了dq法以及用dq法解箱梁剪力滞控制微分方程的几个实例,说明了dq法在求解变截面箱梁剪力滞中的优势;第四章介绍了有限元软件ansys ,以及用ansys分析桥梁受力情况的几个例子,说明了用ansys中相关单元分析桥梁的可行性:第五章构造单箱双室、三室、四室的悬臂梁、简支梁模型,分别分析了他们在集中荷载、均布荷载作用下的受力情况。
4.In short , the analysis of arc - tip fracture shows that : the initiation of void - mode fracture can be judged by vgc criterion , or by j " . according to sx criterion ; fracture direction of void - mode fracture can be determined by ctod and peak value line of stress triaxiality . the mesomechanics mechanism of shear - mode fracture need further study , and analysis found direction of plastic belt is consistent with the direction of shear - mode fracture
综上所述,本文通过对圆弧尖端裂纹的分析表明:对于韧窝型断裂的起裂,可以依据-复合型断裂的sx准则按照i ~ 1来预测起裂载荷,也可用v _ ( gc )判据来预测起裂载荷,二者结果相近;对于韧窝型断裂的断裂角,用ctod矢量方向和三轴度脊线方向判断均和试验结果基本。
5.In view of the inconsistency between the direction of shear stress and total stress components and the normal direction of the corresponding inclined plane , a new three dimensional figure was proposed , which can give direct and intuitionistic description for the magnitude of these stress components
针对剪应力、全应力作用方向与斜面的法向并不一致的问题,给出了一种能够直接描述不同斜面上正应力、剪应力和全应力变化的三维图形,该图形能够非常直观地表示正应力、剪应力以及全应力数值的变化。
