Abstract

Three dimensional finite element studies on three point bend specimens were carried out to determine the fracture toughness using the J-integral method for three dental composite materials. The stress intensity factor results obtained from the three dimensional finite element analysis are in good agreement with 2D-plane strain and experimental data. In addition, scanning electron microscopy studies were carried out to observe the fracture surfaces and to find the relation of microstructure to its fracture toughness values for the three dental composite resins.
