The phase-field approach is a very powerful technique to model and simulate complex fracture phenomena under various loading conditions in multi-field settings and across the scales. Due to its flexibility, this methodology has gained wide interest in the engineering and applied mathematics communities, especially in the past decade. This mini-symposium provides a forum for the discussion and exchange of ideas related to new advances and applications of the phase-field approach to fracture, corrosion, and fatigue in engineering. It welcomes contributions on phase-field modeling of fracture, including brittle, cohesive, and ductile fracture in solid and structural mechanics. Research results on basic aspects of phase-field formulations and of their numerical implementation, experimental validation as well as extensions to novel and/or more complex settings and relevant applications are all welcome.
