- Abstract
- This paper presents an analysis of the extensive experimental work aimed at assessing the influence of macrostructural parameters, such as specimen dimensions, on brittle fracture. Two aspects of characterization of the Fracture Process Zone (FPZ) in quasi-brittle materials such as concrete are developed in this study. The fracture process was monitored by optical and acoustic imaging techniques. Two forms of comparisons of the test results with respect to the specimen and aggregates size were adopted. A comparative study is done between Acoustic Emission (AE) and Scanning Electron Microscope (SEM) to understand the micro level aspect of the FPZ in a concrete beam. The results obtained from the two experimental studies have shown that there is a small divergence between experimental results (SEM and AE). This may be related to some details during the sample analysis.
