论文摘要
预计所有系统旨在在其要求的一生中履行其功能。然而，系统的故障可能会发生，不幸的是，对于真空系统而言，这也是正确的。从机械的角度来看，屈曲，通过疲劳裂纹传播泄漏，在不平衡的真空力下固定支撑的破裂...可能发生。为了很好地理解和预测结构的行为，必须首先了解材料的机械行为及其故障模式。这是在文档的第一部分中提出的。然后，讨论了真空系统的结构行为及其与材料特性的关系。最后，针对给定应用程序进行材料选择的指南很粗糙。
All systems are expected to be designed to fulfil their functions over their requested lifetime. Nevertheless, failure of a system may occur, and this is unfortunately, true also for vacuum systems. From a mechanical point of view, buckling, leak by fatigue crack propagation, rupture of a fixed support under unbalanced vacuum force... may happen. To well understand and anticipate the behaviour of a structure, it is mandatory to first understand the mechanical behaviour of materials as well as their failure modes. This is presented in a first part of the document. Then, the structural behaviour of a vacuum system and its relationship with the material properties is discussed. Finally, guidelines for the material selection for a given application are roughed out.
