CanFrac Verification

The publication “Modeling discrete fractures in continuum analysis and insights for fracture propagation and mechanical behavior of fractured rock” (https://doi.org/10.1016/j.rineng.2019.100070) describes the verification of CanFrac for typical laboratory loading conditions such as triaxial compression, triaxial extension, and Brazilian testing (diametral compression of a rock disc), for both previously unfractured rock and rock with preexisting fractures. The verification analyses show that CanFrac can be relied upon for understanding and predicting the mechanical behavior of rock, including fracture initiation, propagation, and coalescence; with or without preexisting fractures.

Additionally, CanFrac has been used to model geotechnical analysis of foundations, hydraulic fracturing, effects of microfractures on the mechanical behavior of concrete, and the response of a concrete dam to earthquake ground motions. The results were published as peer-reviewed papers described under “Publications” menu item (Publications).
