Abstract
Crack growth driven by cyclic loading remains a dominant factor controlling the useful life of engineered structures. This symposium brings together outstanding researchers to highlight new advances in understanding the mechanisms of fatigue crack growth and in numerical modeling of the mechanisms. The papers address traditional metallic materials and new advanced materials (metallic foams and biological tissues), residual stresses, mixed-mode loading, threshold and closure effects, and variable amplitude loading. Experimental and computational results described in the papers cover a length-scale that varies from nano-meters to meters.		 INDEX

Abstract
The Authors of the papers submitted to the above Mini Symposium should try and show how the use of numerical methods on computers has assisted the application of fatigue data to practical engineering problems involving fatigue. As an example, the development of standard load histories (spectra) would not have been possible without using computers for the necessary calculations. Further, the fatigue life of cracked structures (for instance, pressure vessels) can be estimated by applying numerical methods.
