Group Travel for U.S. Participants in the International Conference on Recent Developments on the Fracture of Concrete, Rock, Cardiff, United Kindgom, Sept. 20-22, 1989

提供的资金用于支付校长的部分旅费 调查员和其他11名研究人员在该领域的研究 断裂力学在水泥和骨料中的应用 参加国际会议的材料 混凝土断裂与岩石断裂的研究进展 1989年9月20日至22日在卡迪夫举行。 这次会议， 在年度系列的第五，是由RILEM委员会，TC- 89 FMT，混凝土断裂力学，试验方法; TC-FMA， 混凝土断裂力学的应用; 混凝土和岩石的断裂; ACI 446，断裂力学; 国际岩石力学学会 本次会议 为技术讨论提供了一个国际论坛， 用断裂力学方法描述裂纹 在混凝土和岩石中的扩展和断裂 复杂的压力状态。 一个特别重要的特点是， 这次会议和前两次会议将汇集 主要从事混凝土研究的研究人员 以岩石为主，作为试验、评价和应用 问题是非常相似的。 值得注意的是，欧洲和 日本人在实施这些措施方面取得了很大进展， 概念融入法医工程和设计实践。 因为这 研究领域也在美国迅速发展， 各国、各小组之间关于正式和 非正式的水平是非常可取的。

Funds are provided for partial travel support for the Principal Investigator and eleven other researchers in the field of fracture mechanics applications to cementitious and aggregative materials to participate in the International Conference on Recent Developments on the Fracture of Concrete and Rock to be held in Cardiff, September 20-22, 1989. This conference, the fifth in an annual series, is supported by RILEM committees, TC- 89 FMT, Fracture Mechanics of Concrete, Test Methods; TC-FMA, Fracture Mechanics of Concrete, Applications; SEM subdivision on Fracture of Concrete and Rock; ACI 446, Fracture Mechanics; and the International Society for Rock Mechanics. This meeting provides an international forum for technical discussions on using fracture mechanics methodologies for describing crack propagation and fracture in concrete and rock subjected to complex states of stress. A particularly important feature of this -- and the previous two conferences -- is to bring together researchers working primarily with concrete and those working primarily with rock, as the testing, evaluation and application problems are quite similar. It is noted that the Europeans and Japanese are making great progress toward implementing these concepts into forensic engineering and design practice. As this area of research has also developed rapidly within the United States, interaction between the various groups on formal and informal levels is very desirable.
