Abstract

Modeling of concrete failure under fatigue loading is becoming a field of interest. Possible alternative testing solutions are now being searched. In this paper, the fracture energy for a certain concrete, resulting from three traditional fracture tests, namely three point bending test, wedge-splitting test and modified compact tension test, is investigated.
