These materials include transformation-toughened zirconia which undergoes a stress-induced crystallographic transformation in the vicinity of a propagating crack, microcracking ceramics, and ceramic-fiber reinforced ceramic matrices. Since many of these materials are under consideration for structural applications, understanding fracture in these quasi-brittle materials is essential. Portland cement concrete is a relatively brittle material. As a result mechanical behavior of concrete, conventionally reinforced concrete, prestressed concrete and fiber reinforced concrete is critically influenced by crack propagation. Crack propagation in concrete is characterized by a fracture process zone, microcracking, and aggregate bridging. Such phenomena give concrete toughening mechanisms, and as a result, the macroscopic response of concrete can be characterized as that of a quasi-brittle material. To design super high performance cement composites, it is essential to understand the complex fracture processes in concrete. A wide range of concern in design involves fracture in rock masses an | | 出版日期 | Book 1991 | | 关键词 | materials | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-011-3388-3 | | isbn_softcover | 978-94-010-5498-0 | | isbn_ebook | 978-94-011-3388-3Series ISSN 0168-132X | | issn_series | 0168-132X | | copyright | Springer Science+Business Media Dordrecht 1991 |
