摘要：The diaphragm of steam turbine is one of the main parts of the passage unit for air flowing and the diaphragm of steam turbine is generally made by welding, but during the course of welding, some cracks often have happened, these cracks threaten safety production on the spot, so it is necessary to analyze the strength of steam turbine diaphragm with a crack. For studying its working condition and performance with a crack, the three-dimensional finite element model （FEM） with the software ANSYS 10.0 is established according to the actual working parameters. With the model, the deformation results and stress field results are analyzed and the maximum displacement and stress value are calculated, meanwhile, the maximum stress change with crack depth of steam turbine diaphragm is analyzed. It provides a good foundation for solving the problem in production.

摘要：由party/space/design事务所设计的crack咖啡厅,位于泰国曼谷。咖啡厅设计的最初灵感来源于当人们吃华夫饼时所发出的声音——C-R-A-C-K。出于这样的设想,设计师在此基础上做了想象的延伸,以一只小鸡试图破壳而出的具象概念作为咖啡厅设计的主要理念。crack的总体设计简约独特又不乏时尚感。

摘要：疲劳是零件或结构失效的主要原因.为此设计了一种操作灵活的新型疲劳裂纹修复仪,其可通过可编程控制器和机械臂实现自动工作.纳米材料在低于零件或结构熔点的温度下被用以修复裂纹.裂纹修复仪主要由机身、手柄、相机、喷嘴和活塞组成.其利用激光作为热源,温度传感器对温度进行检测并对纳米材料流通道进行控制.来自外部光源的激光通过喷嘴中心孔照射到工件裂纹处,喷嘴中心孔被粉末通道的出口环绕,粉末出口的方向和激光的焦点重合,在激光加热工件之后喷上粉末,并在材料沉积工序之后进行压力冲击.距离传感器能够使修复过程随着裂纹的发现和探测来进行.本设计结构紧凑,原理简单,可以高效完成裂纹修复.

摘要：This study proposed a prediction formula for the torsional strength enabling to reflect the tensile strength of ultra high performance concrete (UHPC) beams based upon the thin-walled tube theory. The remarkable ductile behavior of UHPC can also be attributed to the steel fiber reinforcement. This feature must be considered to provide rational explanation of the torsional behavior of UHPC structures. In this study, the proposed torsional design adopts a modified thin-walled tube theory so as to consider the tensile behavior of UHPC. And torsion test was conducted on thin-walled UHPC box beams to validate the proposed formula through comparison of the predicted torsional strength with the experimental results. The comparison of the predicted values of the cracking torque and torsional moment resistance with those observed in the torsional test of UHPC verified the validity of the design method. The contribution of the steel fibers to the torsional strength and cracking load was larger than that of the stirrups, but the stirrups appeared to contribute additionally to the torsional ductility. Accordingly, it is recommended that design should exploit effectively the contribution of the steel fiber rather than arrange a larger number of stirrups in UHPC structures subjected to torsion.
