Abstract

In this study a model of microcrack occurred during the fracture process of mortar or concrete is presented and verified using Rigid Bodies Spring Model (RBSM), which is characterise by tensile and shear springs. A model of mortar or concrete specimen under compressive and tensile actual loading was considered. Based on the Moment Tensor Analysis of Acoustic Emission, information about crack location and crack type are obtained. Also cracks are classified into tensile cracks or shear cracks. Consequently, there is good agreement between analysed results and experimental results. Thus RBSM could be suggest being useful for the calculation of fracture basic criteria of concrete.
