Identification of mechanical fracture parameters for estimation of statistical properties of geopolymer mortars
Original language description
The aim of this paper is to identify statistics of mechanical fracture parameters based on evaluation of fracture tests records. The prism specimens made from fine-grained composite based on alkali activated fly ash matrix with nominal dimension 40 × 40 × 160 mm and initial central edge notch were subjected to fracture tests in three-point bending configuration. The dependence of load F on displacement d (deflection in the middle of the span length) was recorded during the fracture tests. The obtained F−d diagrams and specimen dimensions were used as input data for parameters identification via inverse analysis based on artificial neural network, which aim is to transfer the fracture test response data to the desired material parameters. In this paper, the modu-lus of elasticity, tensile strength and fracture energy values were identified and subsequently compared with values obtained based on fracture test evaluation using effective crack model and work-of-fracture method.
