    法国国家科学研究中心(French National Centre for Scientific Research),巴黎高等师范学院机械工程实验室研究室主任,教授Jacques Lamon,应邀来我校进行短期访问和交流,计划于近期做客研究生国际讲堂,讲授脆性陶瓷和复合材料的脆性断裂和损坏:统计概率方法全英文课程。相关信息如下:

    课程名称:

    Brittle fracture and damage of brittle materials and composites: statistical-probabilistic approaches(脆性陶瓷和复合材料的脆性断裂和损坏:统计概率方法)

    授课计划:见附件

    授课内容:

    本课程侧重于研究脆性断裂的概率方法,主要讨论的问题如下:

    总缺陷数量对断裂强度的影响

    脆性断裂的主要概率统计方法

    使用概率统计方法预测由缺陷数量引起的失效和影响

    概率统计方法在组件设计中的应用

    定义缺陷强度分布的统计参数的估计方法

    概率统计方法延伸到连续纤维增强陶瓷基复合材料的损坏和失效

    讨论几个断裂预测的例子,有助于更好地理解和解决问题。

     

    该课程通过理论和实验两个方面提出了解决断裂或设计问题的概念、工具和方法。因此,对于许多脆性材料,通过适当的方法引入工业系统中,不仅有效地预测使用中材料的破裂或损坏条件,而且还预测这些条件发生的相关风险。

    The series of lectures focuses on probabilistic approaches to brittle fracture. The followingissues are discussed successively:

    —The effects of flaw populations on fracture strength.

    —The main statistical-probabilistic approaches to brittle fracture.

    —The use of these methods for predictions of failure and effects induced by flaw populations.

    —The application of these methods to component design.

    —The methods of estimation of statistical parameters that define flaw strength distributions.

    —The extension of these approaches to damage and failure of continuous fiber reinforcedceramic matrix composites.

    —Several examples of failure predictions are discussed. They are useful for a betterunderstanding or for solving problems.

    The course tackles theoretical and experimental aspects. It proposes concepts, tools andmethods to solve problems of fracture or design. Thus, for many brittle materials, theirintroduction in industrial systems requires appropriate approaches that are efficient to predictnot only the conditions of fracture or damage in service, but also the associated risk ofoccurrence of these conditions.
