Matrix-free phase-field modeling of fracture in micromechanical testing simulations of inelastic materials

Resolving steep damage gradients across diffuse cracks in the phase-field modeling of fracture favors the use of high-order finite elements, for which matrix-free methods can provide superior performance and scalability.
