Cornell Fracture Group

The CFG members include Profs. Tony Ingraffea and Derek Warner, and their research associates, graduate students, and post-docs. The mission of the Cornell Fracture Group is to create, to verify, and to validate computational simulation systems for fracture control in engineered systems. We have included some tutorial and demo simulations to illustrate some of the features and capabilities of the simulators. An equally important focus of the group is education at all levels.  Our current and past research has focused on both experimental testing and numerical simulation of fatigue and fracture in a variety of materials, from the quantum to the engineered structure length scales. The research has been documented and cited in a number of theses, conference proceedings, reports, and journal articles.
