This paper deals with the prediction of high-cycle fatigue behaviour for four different materials (a 7075-T6 alloy, a Ti-6Al-4V alloy, JIS S10C steel and a 0.4%C steel) using Chapetti´s approach to estimate the fatigue-crack ...

A numerical method for 2D LEFM crack propagation simulation is presented. This uses a Lepp–Delaunay based mesh refinement algorithm for triangular meshes which allows both the generation of the initial mesh and the local ...

Improvements on prognostics and health management (PHM) techniques are extremely important in order to prevent system failure and reduce costs with maintenance and machine downtime. In the particular case of system components ...

The Dual Boundary Element Method (DBEM) is used in this work to model the micro mechanics of fatigue crack propagation in austempered ductile iron (ADI). Emphasis is put in devising accurate procedures for the evaluation ...

Thermal transformations on microalloyed steels can produce multiphase microstructures with different amounts of ferrite, martensite, bainite and retained austenite. These different phases, with distinct morphologies, are ...
