Calculation of Mechanical Fracture Parameters of Chevron Notched Core Based Concrete Specimen: Software CheF

Abstract:

The structural concrete can be also characterized via parameters obtained by evaluation of fracture tests. Therefore, this paper presents software CheF developed in Java programming language, designed for evaluation of three-point bending fracture tests of core based concrete specimens with chevron type notch. The records of fracture tests in form load vs. displacement and load vs. crack mouth opening displacement diagrams are analysed by software CheF to obtain values of selected mechanical fracture parameters: modulus of elasticity E, fracture toughness K_Ic, and fracture energy G_F, determined based on the linear elastic fracture mechanics approach and work-of-fracture method.
