The study and design of cyclically loaded structures cannot neglect the evaluation of their fatigue behavior. Today numerical prediction tools allow adopting, in various industrial fields, refined and consolidated procedures for the assessment of cra

To take into account the weakening effect of defects clusters in real microstructures, we propose a multiscale model in a two-dimensional setting. At a small scale, single defects are described as elliptical voids randomly distributed and randomly or

Radial basis functions (RBF) mesh morphing is a well established approach to quickly update an existing finite element analysis (FEA) mesh so that new shapes can be adapted and related performances explored. The RBF in fact allow to adapt the volume

Corrosion is one of the most destructive on the environment and also on our safety. Not only does the microstructure influence the severity of corrosion, but also does many other chemical and mechanical factors such as fatigue. For this reason, the a

We develop a hierarchical model for the description of the stress state inside a cluster of degenerated graphite in spheroidal cast iron. The model is based on the following simplifying assumptions: at the microscale, the graphite particles are viewe

During the casting process and solidification of ductile iron castings, a heterogeneous microstructure is formed throughout the casting. This distribution is strongly influenced by the item geometry and the process related factors, as chemical compos

In this presentation, we will summarize the main results of a research activity aiming at predicting the size of the defect at the origin of fatigue failure in large spheroidal cast iron presses. The endurance limit of the material is largely influen

The formulation of a probability-stress-life (P-S-N) curve is a necessary step beyond the basic S-N relation when dealing with reliability. This paper presents a model, relevant to materials that exhibits a fatigue limit, which considers the number o

We propose a finite element methodology to consider local material properties for large cast iron components in shape optimization. We found that considering local strength instead of uniform strength within shape optimization brings to different res
