The failure of materials and interfaces is mediated by cracks, almost singular dissipative structures that propagate at velocities approaching the speed of sound. Crack initiation and subsequent propagation-the dynamic process of fracture-couples a wide range of time and length scales. Crack dynamics challenge our understanding of the fundamental physics processes that take place in the extreme...

 Fatigue life of deck longitudinals oil tankers is analysed based on linear elastic fracture mechanics. A parametric formulation for the estimation stress intensity factors and Paris-Erdogan law are applied. Long-term effects corrosion modelled regression equations fitted to thickness measurements made during inspections two tankers. Parametric studies performed in order investigate impor...
Fracture propagation involves the coupling of many length scales ranging from the sample loading geometry to the molecular level. In brittle materials, the length scales of the damage process zone are reduced to a submicrometric scale and the coupling with the macroscopic scale is expected to be the domain of linear elastic fracture mechanics (LEFM). However, although 2D elastic analyses are ge...
