Crack Classification in Notched Concrete Beams using Acoustic Emission Technique

Abstract: Cracking of concrete is a major serviceability problem in reinforced concrete (RC) structures. Linear fracture laws and strength based theories are limited in application to concrete because of the sizeable fracture process zone and the inelastic growth of crack openings and crack length. In order to build sustainable structures, the study of fracture mechanism is necessary. As concrete is generally classified as quasi-brittle material, which is a heterogeneous and multiphase material, the fracture process is very complex since it consists of main cracks with various branches like primary and secondary cracks and micro-cracks. It is necessary to obtain more data describing the characteristics of fracture such as types of cracks so that, adequate steps can be taken to control and prevent the failure in concrete structures. Thus, the present paper enlightens the applicability of Acoustic Emission (AE) technique for classification of cracks developed in beams subjected to three point loading. The experimental results indicate that RA value analysis of AE technique is a powerful technique.
