Rupture Behaviour of Concrete due to Fracture Applications of Static Loading on a Structure of Plane Concrete

Abstract

In this Paper, the main focus is on the mechanics of fracture applications to static loading on a structure of plane concrete. The model is based on the mechanics of fracture that is basically creating on levels of constitutive. On the basis of physical manner, the fracture zone energy is consumed by the matrials of micro cracking. Fractures main sources are the result of stress concentrations Cracks where quasi-brittle, brittle, ductile are the classification of these materials. Failure of tensile (mode-I)is the main failure of plane concrete in the research. The main discussed points in this research work are: energy of fracture, compressive strength relationship, normal concretes behaviour, and effects of size of aggregate. The compressive strength range is 33MPa to 44MPa. Fracture energy decreases as the size of coarse aggregate is increases. If change the specimen size, then load will be increase but energy of fracture will be decreased because of cross section area will be changed. The fracture energy released increases with decrease in maximum aggregate size. In the current study, it was concluded that fracture energy dependent on the maximum aggregate size and the size of specimen.
