Description

The fracture problem in concrete has been studied in great depth over the past thirty years. There have been many experimental and analytical attempts to calculate a work of fracture and to gain an understanding of the complex mechanisms of concrete fracture. An emerging theme is the intrinsic three-dimensional nature of the damage that occurs in loaded concrete. This has led to an increase in the amount of interior studies conducted. The insides of concrete have been exposed over the years by, among others, acoustic emission techniques, ultrasonics, dye penetration and radiography [1]. Most recently, x-ray microtomography has been used in order to see into the heart of concrete failure [2].
