The determination of the fatigue crack propagation curve is an essential part of the fracture mechanics design approach. Residual strength calculation procedures have obvious shortcomings, but the prediction of fatigue crack propagation characteristics is even less accurate, despite the vast amount of research that has been done on this subject.

Fatigue failure is caused by the initiation of micro cracks from small defects in a material, followed by their propagation resulting in the formation of macro cracks, where the magnitude of applied stress may be lower than the yielding stress but the load is repeatedly applied to the material.

Fracture-related damage is estimated at more than $10 billion annually in the United States. It is a major safety concern for airline industries, electric utilities, off-shore oil recovery operations, and many other industries. Computational simulation of crack propagation should be useful for the analysis of existing problems, and for the design of ...

Crack Speed During Dynamic Crack Propagation
2003A crack of length 20 mm propagates in a large steel plate under a constant stress of 400 MPa. The dynamic toughness of the material KID can be expressed by the following empirical equation $$ {K_{ID}} = \frac{{{K_{IA}}}}{{1 - {{\left( {\frac{V}{{{V_\ell }}}} \right)}^m}}} $$ (1) where KIA is the arrest toughness of the material, VL is the ...
