| Outline of Final Research Achievements |
A method for simulating fracture behavior of concrete and reinforced concrete using a damage model based on fracture mechanics was developed. An outstanding feature of the method is the formulation combined with fracture mechanics of concrete and damage mechanics of materials. Several numerical resulted reveal that the proposed method allowed the simulation of 3-dimensional fracture behavior in meso-scale, and good agreement was found between the numerical and experimental results.
To investigate experimentally the fracture process of concrete, a measuring method based on digital image correlation was developed. The experimental results showed that the crack propagation behavior in concrete's meso-structure could be measured and the crack opening behavior could also be visualized.
