Fracture criteria play a very important role in predicting crack propagation behavior and life
evaluation of cracked bodies. In this paper, mixed mode I-II fracture criteria in the framework …

Understanding the inconsistent rock fracture toughness (K Ic) measurement results from
different test specimen geometries helps provide suitable fracture parameters for …

In this study, the cracked straight through Brazilian disc (CSTBD) specimen was applied to
study the I/II mixed mode static fracture of diorite. The fracture load and fracture toughness …

The cracked chevron notched semi-circular bending (CCNSCB) method for measuring
mode I fracture toughness of rocks has many favorable properties similar to those of the …

The cracked chevron notched Brazilian disc (CCNBD) specimen is a suggested testing
method to measure Mode-I fracture toughness of rocks by ISRM, which is widely adopted in …

The semi-circular bend (SCB) method suggested by International Society for Rock
Mechanics (ISRM) is demonstrated to yield much conservative mode I fracture toughness. A …

In this paper two circular shape test specimens are designed and examined for experimental
determination of mode I fracture toughness (K Ic) in different modified hot mix asphalt (HMA) …

The effects of specimen geometry on mode I and mode II fracture toughness (ie, K Ic and K
IIc), and the ratio of K IIc to K Ic for a given rock material were derived on the basis of a …

In this work, the support vector regression method is combined with six metaheuristic
optimization models of particle swarm optimization, grey wolf optimization, multiverse …

In this paper, a modified mixed mode fracture model called the generalized strain energy
density criterion is proposed. The criterion uses three key crack parameters including: the …
