Micromechanics-based variational phase-field modeling of Brazilian splitting tests KU Leuven
The simulation of the Brazilian splitting test can be challenging due to the presence of stress concentrations near the load points, which can lead to numerical problems and convergence issues. This paper aims to realistically model the Brazilian splitting test on mortar samples under monotonic loading, employing a micromechanics-based variational phase-field formulation. A micromechanics-based phase-field model connects the field variables at ...
