摘要：

A new criterion of static-dynamic state mixed mode brittle fracture initiation in rock is suggested, i. e. the distortion strain energy criterion. When t→∞, the static-state distortion strain energy criteria and the formula for determiming static-state fracture angle are obtained. The new static-state criterion, suggested by authors, is in good agreement with the author’s experimental results. In addition, the relative accuracy of three current fracture theories and the new criterion in predicting static-state mixed-mode initiation fracture loading and fracture angle in rock have been evaluated experimentally.
