چکیده
In this research, the fracture behavior of 3 mol% yttria-stabilized tetragonal zirconia polycrystals (3Y-TZP) dental ceramics is investigated. The focus is on the tetragonal (t) to monoclinic (m) phase transformation using ABAQUS and bond-based peridynamics. We conducted two-dimensional simulations of a single grain undergoing uniform dilational expansion within a homogeneous m-phase environment. The effects of transformation time, biaxial stress, and strains on fracture were analyzed. It was found that increasing stress in the surrounding t-phase elevated the elastic strain energy associated with the transformation. By varying stress from -1.1 GPa to 400 MPa, elastic strain energy started to decrease from 3.41, 3.32, 3.11, and 2.85 pJ at fracture strain values of S0= 0.00711, 0.00553, 0.00395, and 0.00237, respectively. These correspond to reductions of 83%, 87%, 90%, and 96%. In addition, damage fractions increased from 0.001, 0.002, 0.003 and 0.004 to 0.005, 0.011, 0.022, and 0.058, respectively. This demonstrates the significant impact of applied stress on the fracture mechanics of 3Y-TZP. Moreover, increasing the elemental parameter S0 from 0.00237 to 0.00711 in the simulations corresponds to a considerable decrease in defect density, resulting in a substantial increase in the total energy required for material division from 0.25 to 2.2 J/m2.
