Cornell Fracture Group
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.
Software Releases and Updates
NOTE: we try to test all links and all versions of all codes, but if
you find a problem - please send us email.
If you download and use the software made available here,
please read the Policy Statement on the Software page. Also please
read the News&FAQs if you have trouble using
the software, especially CYGWIN executables. We will attempt to answer questions or fix problems in
the software, but we are not obligated to provide such service. If you do
ask for help with a particular problem, please provide as much detail as
possible including input files, drawings, etc. The software that is
provided here is intended for people with experience in fracture mechanics
and boundary or finite elements. Please do not ask us for items that
are not made available here - these types of requests will likely be
