Limit and shakedown analyses allowing for limited ductility

基于极限和安定概念的直接法结构完整性评估提供了关于其失效载荷的重要信息。本项目旨在通过将有限延性的影响纳入分析中来克服这种方法的严重缺点。将开发新的配方和有效的算法。这些工具将被用来提供一个更好的理解有限的延性的影响，至关重要的有限的延性结构在复杂的负载下进行适当的安全评估。这种能力对于基础设施设计以及航空技术等战略领域非常重要。

The integrity assessment of structures by direct methods, founded on limit and shakedown concepts, provides vital information about their failure loads. This project aims at overcoming a severe shortcoming of such approaches by incorporating the effects of limited ductility into the analyses. Novel formulations and efficient algorithms will be developed. These tools will be used to provide a better understanding of the implications of limited ductility, vital to a proper safety assessment of limited ductility structures under complex loadings. Such a capability is important in infrastructure design as well as in such strategic areas as the aeronautical technologies.
