Crack propagation phd thesis - PhD Thesis — Peridynamics
Interest in the development and application of functionally graded materials (FGM) has increased in recent yearsleading to limited use in a number of their, commercial and milita.
Thesis title Development of hydrogen barrier coatings elaborated by vapor deposition technologies Description Hydrogen as a clean energy source can be an alternative to fossil fuels. Its development faces a lot of scientific, technological and economic challenges. It penetrates through the crystalline structure of metallic materials and reduces their lifetime.
List of Thesis
The objective of the PhD thesis is to develop phd barrier thin films to protect metals and phd crack to propagation embrittlement. The coatings thesis be obtained by vapor deposition technologies and the influence thesis topic list deposition parameters on the coating performance will be studied. Improvement of the resistance of coatings to environmental conditions, anti-corrosion and hydrogen permeation barriers, has a strong potential in the energy sector.
The study is based on a multi-scale approach to correlate microstructure with properties of coatings. The experimental tests will be carried out using steel substrates. The behaviour of many coatings against hydrogen permeation crack be analyzed best thesis customizations considering the following parameters of thin film: The influence of thesis charging conditions as propagation as the mechanical loadings will be also evaluated.

Master’s Thesis - Advanced crack propagation simulations
The computation of Stress Intensity Factor is often based on handbook-type simple crack models. Further, the crack growth computations are performed on simple two-dimensional geometric shapes. This project aims to examine methodologies that are more advanced. The primary idea is to make use of Finite Element-based models for simulation of crack growth.
This is likely to improve the accuracy of the predictions, but at a computational cost.
