Crack models

Blumenauer gives a brief explanation of the most commonly used crack models in [1]. Such crack models provide the basis for the basic concepts of fracture mechanics and the fracture mechanics material testing based on them, with the aim of determining fracture mechanics parameters using fracture mechanics test specimens. The best known crack models are [1-3]:

Other crack models that involve a different approach are the models named after the authors of:

BILBY, COTTRELL and SWINDEN (BCS crack model) [4]
HUTCHINSON; RICE and ROSENGREEN (HRR crack model) [5,6]
