Microstructure and Crack Initiation, Propagation and Localization in Concrete
The goal of this research was to study the physical processes such as crack formation and localization affecting the performance of concrete. To clearly establish relation between macroscopic deformations and microscopic damage mechanisms, model concrete specimens with prefabricated microstructures were stressed and examined using Acoustic Emission and Lase Holography. The emphasis of the study was on a detailed observation of microstructure and crack growth under well defined observation of microstructure and crack growth under well defined boundary conditions. Fracture mechanics concepts were applied to understand various experimentally observed phenomena for different modes. Keywords: Crack propagation; Acoustic emission; Concrete fractures; Experiments; Laser holographic interferometry; Speckle photography. (KT)
