混凝土断裂力学及其研究现状

Progress in Mechanics of Concrete Fracture

混凝土断裂力学是20世纪60年代基于金属断裂力学的基本理论基础而发展起来的固体力学分支.它主要研究含裂缝体的混凝土材料和混凝土结构的破坏过程以及裂缝传播规律,建立断裂准则,探讨如何控制和防止混凝土结构断裂破坏的措施.综述了断裂力学及混凝土断裂力学的产生和发展,对国内外研究混凝土断裂力学的现状进行了介绍和讨论.

Mechanics of Concrete Fracture is a new branch of solid mechanics which arose in 1960's. It deals with the damage process and the fracture spreading rules of fractured Concrete materials and structures, and tries to establish the norms of fracture and to find out how to prevent concrete structures from cracking. Mechanics of concrete fracture is theoretically based on mechanics of metal fracture. This paper makes a survey of the emergence and development of mechanics of fracture and mechanics of concrete fracture and discusses the progress in the field of the latter.
